- /** - Promise objects represent the eventual result of an asynchronous operation. The - primary way of interacting with a promise is through its `then` method, which - registers callbacks to receive either a promise's eventual value or the reason - why the promise cannot be fulfilled. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. - - Promises can also be said to *resolve* a value. If this value is also a - promise, then the original promise's settled state will match the value's - settled state. So a promise that *resolves* a promise that rejects will - itself reject, and a promise that *resolves* a promise that fulfills will - itself fulfill. - - - Basic Usage: - ------------ - - ```js - var promise = new Promise(function(resolve, reject) { - // on success - resolve(value); - - // on failure - reject(reason); - }); - - promise.then(function(value) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Advanced Usage: - --------------- - - Promises shine when abstracting away asynchronous interactions such as - `XMLHttpRequest`s. - - ```js - function getJSON(url) { - return new Promise(function(resolve, reject){ - var xhr = new XMLHttpRequest(); - - xhr.open('GET', url); - xhr.onreadystatechange = handler; - xhr.responseType = 'json'; - xhr.setRequestHeader('Accept', 'application/json'); - xhr.send(); - - function handler() { - if (this.readyState === this.DONE) { - if (this.status === 200) { - resolve(this.response); - } else { - reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); - } - } - }; - }); - } - - getJSON('/posts.json').then(function(json) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Unlike callbacks, promises are great composable primitives. - - ```js - Promise.all([ - getJSON('/posts'), - getJSON('/comments') - ]).then(function(values){ - values[0] // => postsJSON - values[1] // => commentsJSON - - return values; - }); - ``` - - @class Promise - @param {function} resolver - Useful for tooling. - @constructor - */ - function lib$es6$promise$promise$$Promise(resolver) { - this._id = lib$es6$promise$promise$$counter++; - this._state = undefined; - this._result = undefined; - this._subscribers = []; - - if (lib$es6$promise$$internal$$noop !== resolver) { - if (!lib$es6$promise$utils$$isFunction(resolver)) { - lib$es6$promise$promise$$needsResolver(); - } - - if (!(this instanceof lib$es6$promise$promise$$Promise)) { - lib$es6$promise$promise$$needsNew(); - } - - lib$es6$promise$$internal$$initializePromise(this, resolver); - } - } - - lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default; - lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default; - lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default; - lib$es6$promise$promise$$Promise.reject = lib$es6$promise$promise$reject$$default; - lib$es6$promise$promise$$Promise._setScheduler = lib$es6$promise$asap$$setScheduler; - lib$es6$promise$promise$$Promise._setAsap = lib$es6$promise$asap$$setAsap; - lib$es6$promise$promise$$Promise._asap = lib$es6$promise$asap$$asap; - - lib$es6$promise$promise$$Promise.prototype = { - constructor: lib$es6$promise$promise$$Promise, - - /** - The primary way of interacting with a promise is through its `then` method, - which registers callbacks to receive either a promise's eventual value or the - reason why the promise cannot be fulfilled. - - ```js - findUser().then(function(user){ - // user is available - }, function(reason){ - // user is unavailable, and you are given the reason why - }); - ``` - - Chaining - -------- - - The return value of `then` is itself a promise. This second, 'downstream' - promise is resolved with the return value of the first promise's fulfillment - or rejection handler, or rejected if the handler throws an exception. - - ```js - findUser().then(function (user) { - return user.name; - }, function (reason) { - return 'default name'; - }).then(function (userName) { - // If `findUser` fulfilled, `userName` will be the user's name, otherwise it - // will be `'default name'` - }); - - findUser().then(function (user) { - throw new Error('Found user, but still unhappy'); - }, function (reason) { - throw new Error('`findUser` rejected and we're unhappy'); - }).then(function (value) { - // never reached - }, function (reason) { - // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. - // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. - }); - ``` - If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. - - ```js - findUser().then(function (user) { - throw new PedagogicalException('Upstream error'); - }).then(function (value) { - // never reached - }).then(function (value) { - // never reached - }, function (reason) { - // The `PedgagocialException` is propagated all the way down to here - }); - ``` - - Assimilation - ------------ - - Sometimes the value you want to propagate to a downstream promise can only be - retrieved asynchronously. This can be achieved by returning a promise in the - fulfillment or rejection handler. The downstream promise will then be pending - until the returned promise is settled. This is called *assimilation*. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // The user's comments are now available - }); - ``` - - If the assimliated promise rejects, then the downstream promise will also reject. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // If `findCommentsByAuthor` fulfills, we'll have the value here - }, function (reason) { - // If `findCommentsByAuthor` rejects, we'll have the reason here - }); - ``` - - Simple Example -

-/** - Promise objects represent the eventual result of an asynchronous operation. The - primary way of interacting with a promise is through its `then` method, which - registers callbacks to receive either a promise's eventual value or the reason - why the promise cannot be fulfilled. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. - - Promises can also be said to *resolve* a value. If this value is also a - promise, then the original promise's settled state will match the value's - settled state. So a promise that *resolves* a promise that rejects will - itself reject, and a promise that *resolves* a promise that fulfills will - itself fulfill. - - - Basic Usage: - ------------ - - ```js - var promise = new Promise(function(resolve, reject) { - // on success - resolve(value); - - // on failure - reject(reason); - }); - - promise.then(function(value) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Advanced Usage: - --------------- - - Promises shine when abstracting away asynchronous interactions such as - `XMLHttpRequest`s. - - ```js - function getJSON(url) { - return new Promise(function(resolve, reject){ - var xhr = new XMLHttpRequest(); - - xhr.open('GET', url); - xhr.onreadystatechange = handler; - xhr.responseType = 'json'; - xhr.setRequestHeader('Accept', 'application/json'); - xhr.send(); - - function handler() { - if (this.readyState === this.DONE) { - if (this.status === 200) { - resolve(this.response); - } else { - reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); - } - } - }; - }); - } - - getJSON('/posts.json').then(function(json) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Unlike callbacks, promises are great composable primitives. - - ```js - Promise.all([ - getJSON('/posts'), - getJSON('/comments') - ]).then(function(values){ - values[0] // => postsJSON - values[1] // => commentsJSON - - return values; - }); - ``` - - @class Promise - @param {function} resolver - Useful for tooling. - @constructor -*/ -function Promise(resolver) { - this._id = counter++; - this._state = undefined; - this._result = undefined; - this._subscribers = []; - - if (noop !== resolver) { - if (!isFunction(resolver)) { - needsResolver(); - } - - if (!(this instanceof Promise)) { - needsNew(); - } - - initializePromise(this, resolver); - } -} - -Promise.all = all; -Promise.race = race; -Promise.resolve = Resolve; -Promise.reject = Reject; -Promise._setScheduler = setScheduler; -Promise._setAsap = setAsap; -Promise._asap = asap; - -Promise.prototype = { - constructor: Promise, - -/** - The primary way of interacting with a promise is through its `then` method, - which registers callbacks to receive either a promise's eventual value or the - reason why the promise cannot be fulfilled. - - ```js - findUser().then(function(user){ - // user is available - }, function(reason){ - // user is unavailable, and you are given the reason why - }); - ``` - - Chaining - -------- - - The return value of `then` is itself a promise. This second, 'downstream' - promise is resolved with the return value of the first promise's fulfillment - or rejection handler, or rejected if the handler throws an exception. - - ```js - findUser().then(function (user) { - return user.name; - }, function (reason) { - return 'default name'; - }).then(function (userName) { - // If `findUser` fulfilled, `userName` will be the user's name, otherwise it - // will be `'default name'` - }); - - findUser().then(function (user) { - throw new Error('Found user, but still unhappy'); - }, function (reason) { - throw new Error('`findUser` rejected and we're unhappy'); - }).then(function (value) { - // never reached - }, function (reason) { - // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. - // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. - }); - ``` - If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. - - ```js - findUser().then(function (user) { - throw new PedagogicalException('Upstream error'); - }).then(function (value) { - // never reached - }).then(function (value) { - // never reached - }, function (reason) { - // The `PedgagocialException` is propagated all the way down to here - }); - ``` - - Assimilation - ------------ - - Sometimes the value you want to propagate to a downstream promise can only be - retrieved asynchronously. This can be achieved by returning a promise in the - fulfillment or rejection handler. The downstream promise will then be pending - until the returned promise is settled. This is called *assimilation*. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // The user's comments are now available - }); - ``` - - If the assimliated promise rejects, then the downstream promise will also reject. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // If `findCommentsByAuthor` fulfills, we'll have the value here - }, function (reason) { - // If `findCommentsByAuthor` rejects, we'll have the reason here - }); - ``` - - Simple Example - -------------- - - Synchronous Example - - ```javascript - var result; - - try { - result = findResult(); - // success - } catch(reason) { - // failure - } - ``` - - Errback Example - - ```js - findResult(function(result, err){ - if (err) { - // failure - } else { - // success - } - }); - ``` - - Promise Example; - - ```javascript - findResult().then(function(result){ - // success - }, function(reason){ - // failure - }); - ``` - - Advanced Example - -------------- - - Synchronous Example - - ```javascript - var author, books; - - try { - author = findAuthor(); - books = findBooksByAuthor(author); - // success - } catch(reason) { - // failure - } - ``` - - Errback Example - - ```js - - function foundBooks(books) { - - } - - function failure(reason) { - - } - - findAuthor(function(author, err){ - if (err) { - failure(err); - // failure - } else { - try { - findBoooksByAuthor(author, function(books, err) { - if (err) { - failure(err); - } else { - try { - foundBooks(books); - } catch(reason) { - failure(reason); - } - } - }); - } catch(error) { - failure(err); - } - // success - } - }); - ``` - - Promise Example; - - ```javascript - findAuthor(). - then(findBooksByAuthor). - then(function(books){ - // found books - }).catch(function(reason){ - // something went wrong - }); - ``` - - @method then - @param {Function} onFulfilled - @param {Function} onRejected - Useful for tooling. - @return {Promise} -*/ - then: function(onFulfillment, onRejection) { - var parent = this; - var state = parent._state; - - if (state === FULFILLED && !onFulfillment || state === REJECTED && !onRejection) { - return this; - } - - var child = new this.constructor(noop); - var result = parent._result; - - if (state) { - var callback = arguments[state - 1]; - asap(function(){ - invokeCallback(state, child, callback, result); - }); - } else { - subscribe(parent, child, onFulfillment, onRejection); - } - - return child; - }, - -/** - `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same - as the catch block of a try/catch statement. - - ```js - function findAuthor(){ - throw new Error('couldn't find that author'); - } - - // synchronous - try { - findAuthor(); - } catch(reason) { - // something went wrong - } - - // async with promises - findAuthor().catch(function(reason){ - // something went wrong - }); - ``` - - @method catch - @param {Function} onRejection - Useful for tooling. - @return {Promise} -*/ - 'catch': function(onRejection) { - return this.then(null, onRejection); - } -}; diff --git a/node_modules/mongodb/node_modules/es6-promise/lib/es6-promise/promise/all.js b/node_modules/mongodb/node_modules/es6-promise/lib/es6-promise/promise/all.js deleted file mode 100644 index 03033f0..0000000 --- a/node_modules/mongodb/node_modules/es6-promise/lib/es6-promise/promise/all.js +++ /dev/null @@ -1,52 +0,0 @@ -import Enumerator from '../enumerator'; - -/** - `Promise.all` accepts an array of promises, and returns a new promise which - is fulfilled with an array of fulfillment values for the passed promises, or - rejected with the reason of the first passed promise to be rejected.

If no operator is specified, then equality is assumed, - so this operator is optional, but MAY be included. - -For example, the comparator `>=1.2.7` would match the versions -`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` -or `1.1.0`. - -Comparators can be joined by whitespace to form a `comparator set`, -which is satisfied by the **intersection** of all of the comparators -it includes. - -A range is composed of one or more comparator sets, joined by `||`. A -version matches a range if and only if every comparator in at least -one of the `||`-separated comparator sets is satisfied by the version. - -For example, the range `>=1.2.7 <1.3.0` would match the versions -`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, -or `1.1.0`. - -The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, -`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. - -### Prerelease Tags - -If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then -it will only be allowed to satisfy comparator sets if at least one -comparator with the same `[major, minor, patch]` tuple also has a -prerelease tag. - -For example, the range `>1.2.3-alpha.3` would be allowed to match the -version `1.2.3-alpha.7`, but it would *not* be satisfied by -`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater -than" `1.2.3-alpha.3` according to the SemVer sort rules. The version -range only accepts prerelease tags on the `1.2.3` version. The -version `3.4.5` *would* satisfy the range, because it does not have a -prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. - -The purpose for this behavior is twofold. First, prerelease versions -frequently are updated very quickly, and contain many breaking changes -that are (by the author's design) not yet fit for public consumption. -Therefore, by default, they are excluded from range matching -semantics. - -Second, a user who has opted into using a prerelease version has -clearly indicated the intent to use *that specific* set of -alpha/beta/rc versions. By including a prerelease tag in the range, -the user is indicating that they are aware of the risk. However, it -is still not appropriate to assume that they have opted into taking a -similar risk on the *next* set of prerelease versions. - -#### Prerelease Identifiers - -The method `.inc` takes an additional `identifier` string argument that -will append the value of the string as a prerelease identifier: - -```javascript -> semver.inc('1.2.3', 'prerelease', 'beta') -'1.2.4-beta.0' -``` - -command-line example: - -```shell -$ semver 1.2.3 -i prerelease --preid beta -1.2.4-beta.0 -``` - -Which then can be used to increment further: - -```shell -$ semver 1.2.4-beta.0 -i prerelease -1.2.4-beta.1 -``` - -### Advanced Range Syntax - -Advanced range syntax desugars to primitive comparators in -deterministic ways. - -Advanced ranges may be combined in the same way as primitive -comparators using white space or `||`. - -#### Hyphen Ranges `X.Y.Z - A.B.C` - -Specifies an inclusive set. - -* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` - -If a partial version is provided as the first version in the inclusive -range, then the missing pieces are replaced with zeroes. - -* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` - -If a partial version is provided as the second version in the -inclusive range, then all versions that start with the supplied parts -of the tuple are accepted, but nothing that would be greater than the -provided tuple parts. - -* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0` -* `1.2.3 - 2` := `>=1.2.3 <3.0.0` - -#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` - -Any of `X`, `x`, or `*` may be used to "stand in" for one of the -numeric values in the `[major, minor, patch]` tuple. - -* `*` := `>=0.0.0` (Any version satisfies) -* `1.x` := `>=1.0.0 <2.0.0` (Matching major version) -* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions) - -A partial version range is treated as an X-Range, so the special -character is in fact optional. - -* `""` (empty string) := `*` := `>=0.0.0` -* `1` := `1.x.x` := `>=1.0.0 <2.0.0` -* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0` - -#### Tilde Ranges `~1.2.3` `~1.2` `~1` - -Allows patch-level changes if a minor version is specified on the -comparator.

Throws if an - invalid comparison string is provided. -* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if - `v2` is greater. Sorts in ascending order if passed to `Array.sort()`. -* `rcompare(v1, v2)`: The reverse of compare. Sorts an array of versions - in descending order when passed to `Array.sort()`. -* `diff(v1, v2)`: Returns difference between two versions by the release type - (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), - or null if the versions are the same. - - -### Ranges - -* `validRange(range)`: Return the valid range or null if it's not valid -* `satisfies(version, range)`: Return true if the version satisfies the - range. -* `maxSatisfying(versions, range)`: Return the highest version in the list - that satisfies the range, or `null` if none of them do. -* `minSatisfying(versions, range)`: Return the lowest version in the list - that satisfies the range, or `null` if none of them do. -* `gtr(version, range)`: Return `true` if version is greater than all the - versions possible in the range. -* `ltr(version, range)`: Return `true` if version is less than all the - versions possible in the range. -* `outside(version, range, hilo)`: Return true if the version is outside - the bounds of the range in either the high or low direction. The - `hilo` argument must be either the string `'>'` or `'<'`. (This is - the function called by `gtr` and `ltr`.) - -Note that, since ranges may be non-contiguous, a version might not be -greater than a range, less than a range, *or* satisfy a range! For -example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` -until `2.0.0`, so the version `1.2.10` would not be greater than the -range (because `2.0.1` satisfies, which is higher), nor less than the -range (since `1.2.8` satisfies, which is lower), and it also does not -satisfy the range. - -If you want to know if a version satisfies or does not satisfy a -range, use the `satisfies(version, range)` function. diff --git a/node_modules/mongodb/node_modules/mongodb-core/node_modules/require_optional/node_modules/semver/bin/semver b/node_modules/mongodb/node_modules/mongodb-core/node_modules/require_optional/node_modules/semver/bin/semver deleted file mode 100755 index c5f2e85..0000000 --- a/node_modules/mongodb/node_modules/mongodb-core/node_modules/require_optional/node_modules/semver/bin/semver +++ /dev/null @@ -1,133 +0,0 @@ -#!/usr/bin/env node -// Standalone semver comparison program. -// Exits successfully and prints matching version(s) if -// any supplied version is valid and passes all tests. - -var argv = process.argv.slice(2) - , versions = [] - , range = [] - , gt = [] - , lt = [] - , eq = [] - , inc = null - , version = require("../package.json").version - , loose = false - , identifier = undefined - , semver = require("../semver") - , reverse = false - -main() - -function main () { - if (!argv.length) return help() - while (argv.length) { - var a = argv.shift() - var i = a.indexOf('=') - if (i !== -1) { - a = a.slice(0, i) - argv.unshift(a.slice(i + 1)) - } - switch (a) { - case "-rv": case "-rev": case "--rev": case "--reverse": - reverse = true - break - case "-l": case "--loose": - loose = true - break - case "-v": case "--version": - versions.push(argv.shift()) - break - case "-i": case "--inc": case "--increment": - switch (argv[0]) { - case "major": case "minor": case "patch": case "prerelease": - case "premajor": case "preminor": case "prepatch": - inc = argv.shift() - break - default: - inc = "patch" - break - } - break - case "--preid": - identifier = argv.shift() - break - case "-r": case "--range": - range.push(argv.shift()) - break - case "-h": case "--help": case "-?": - return help() - default: - versions.push(a) - break - } - } - - versions = versions.filter(function (v) { - return semver.valid(v, loose) - }) - if (!versions.length) return fail() - if (inc && (versions.length !== 1 || range.length)) - return failInc() - - for (var i = 0, l = range.length; i < l ; i ++) { - versions = versions.filter(function (v) { - return semver.satisfies(v, range[i], loose) - }) - if (!versions.length) return fail() - } - return success(versions) -} - -function failInc () { - console.error("--inc can only be used on a single version with no range") - fail() -} - -function fail () { process.exit(1) } - -function success () { - var compare = reverse ?

For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - -module.exports = Transform; - -var Duplex = require('./_stream_duplex'); - -/*<replacement>*/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/*</replacement>*/ - -util.inherits(Transform, Duplex); - - -function TransformState(options, stream) { - this.afterTransform = function(er, data) { - return afterTransform(stream, er, data); - }; - - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; -} - -function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) - return stream.emit('error', new Error('no writecb in Transform class')); - - ts.writechunk = null; - ts.writecb = null; - - if (data !== null && data !== undefined) - stream.push(data); - - if (cb) - cb(er); - - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } -} - - -function Transform(options) { - if (!(this instanceof Transform)) - return new Transform(options); - - Duplex.call(this, options); - - var ts = this._transformState = new TransformState(options, this); - - // when the writable side finishes, then flush out anything remaining. - var stream = this; - - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; - - // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - this._readableState.sync = false; - - this.once('finish', function() { - if ('function' === typeof this._flush) - this._flush(function(er) { - done(stream, er); - }); - else - done(stream); - }); -} - -Transform.prototype.push = function(chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; - -// This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.
