+# BSON parser
+
+If you don't yet know what BSON actually is, read [the spec](http://bsonspec.org).
+
+This package can be used to serialize JSON documents into the BSON format or the other way around. If you want to use it within the browser, give [browserify](https://github.com/substack/node-browserify) a try (it will help you add this package to your bundle). The current build is located in the `browser_build/bson.js` file.
+
+A simple example of how to use BSON in the browser:
+
+```html
+<script src="./browser_build/bson.js"></script>
+
+<script>
+ function start() {
+ var BSON = bson().BSON
+ var Long = bson().Long
+
+ var doc = { long: Long.fromNumber(100) }
+
+ // Serialize a document
+ var data = BSON.serialize(doc, false, true, false)
+ // De serialize it again
+ var doc_2 = BSON.deserialize(data)
+ }
+</script>
+```
+
+A simple example of how to use BSON in `node.js`:
+
+```js
+var bson = require('bson')
+var BSON = new bson.BSONPure.BSON()
+var Long = bson.BSONPure.Long
+
+var doc = { long: Long.fromNumber(100) }
+
+// Serialize a document
+var data = BSON.serialize(doc, false, true, false)
+console.log('data:', data)
+
+// Deserialize the resulting Buffer
+var doc_2 = BSON.deserialize(data)
+console.log('doc_2:', doc_2)
+```
+
+## API
+
+The API consists of two simple methods to serialize/deserialize objects to/from BSON format:
+=======
+## Installation
+
+`npm install bson`
+
+## API
+
+### BSON serialization and deserialiation
+
+**`new bson.BSONPure.BSON()`** - Creates a new BSON seralizer/deserializer you can use to serialize and deserialize BSON.
+
+ * BSON.serialize(object, checkKeys, asBuffer, serializeFunctions)
+ * @param {Object} object the Javascript object to serialize.
+ * @param {Boolean} checkKeys the serializer will check if keys are valid.
+ * @param {Boolean} asBuffer return the serialized object as a Buffer object **(ignore)**.
+ * @param {Boolean} serializeFunctions serialize the javascript functions **(default:false)**
+ * @return {TypedArray/Array} returns a TypedArray or Array depending on what your browser supports
+
+ * BSON.deserialize(buffer, options, isArray)
+ * Options
+ * **evalFunctions** {Boolean, default:false}, evaluate functions in the BSON document scoped to the object deserialized.
+ * **cacheFunctions** {Boolean, default:false}, cache evaluated functions for reuse.
+ * **cacheFunctionsCrc32** {Boolean, default:false}, use a crc32 code for caching, otherwise use the string of the function.
+ * **promoteBuffers** {Boolean, default:false}, deserialize Binary data directly into node.js Buffer object.
+ * @param {TypedArray/Array} a TypedArray/Array containing the BSON data
+ * @param {Object} [options] additional options used for the deserialization.
+ * @param {Boolean} [isArray] ignore used for recursive parsing.
+ * @return {Object} returns the deserialized Javascript Object.
+
+### ObjectId
+
+**`bson.ObjectId.isValid(id)`** - Returns true if `id` is a valid number or hexadecimal string representing an ObjectId.
+**`bson.ObjectId.createFromHexString(hexString)`** - Returns the ObjectId the `hexString` represents.
+**`bson.ObjectId.createFromTime(time)`** - Returns an ObjectId containing the passed time.
+* `time` - A Unix timestamp (number of seconds since the epoch).
+
+**`var objectId = new bson.ObjectId(id)`** - Creates a new `ObjectId`.
+* `id` - Must either be a 24-character hex string or a 12 byte binary string.
+
+**`objectId.toJSON()`**
+**`objectId.toString()`**
+**`objectId.toHexString()`** - Returns a hexadecimal string representation of the ObjectId.
+
+**`objectId.equals(otherObjectId)`** - Returns true if the ObjectIds are the same, false otherwise.
+
+**`objectId.getTimestamp()`** - Returns a `Date` object containing the time the objectId was created for.
+
+**`objectId.getTimestamp()`** - Returns a `Date` object containing the time the objectId contains.

+ * Defines a Long class for representing a 64-bit two's-complement
+ * integer value, which faithfully simulates the behavior of a Java "Long". This
+ * implementation is derived from LongLib in GWT.
+ *
+ * Constructs a 64-bit two's-complement integer, given its low and high 32-bit
+ * values as *signed* integers. See the from* functions below for more
+ * convenient ways of constructing Longs.
+ *
+ * The internal representation of a Long is the two given signed, 32-bit values.
+ * We use 32-bit pieces because these are the size of integers on which
+ * Javascript performs bit-operations. For operations like addition and
+ * multiplication, we split each number into 16-bit pieces, which can easily be
+ * multiplied within Javascript's floating-point representation without overflow
+ * or change in sign.
+ *
+ * In the algorithms below, we frequently reduce the negative case to the
+ * positive case by negating the input(s) and then post-processing the result.
+ * Note that we must ALWAYS check specially whether those values are MIN_VALUE
+ * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
+ * a positive number, it overflows back into a negative). Not handling this
+ * case would often result in infinite recursion.
+ *

+/**
+ * Defines a Timestamp class for representing a 64-bit two's-complement
+ * integer value, which faithfully simulates the behavior of a Java "Timestamp". This
+ * implementation is derived from TimestampLib in GWT.
+ *
+ * Constructs a 64-bit two's-complement integer, given its low and high 32-bit
+ * values as *signed* integers. See the from* functions below for more
+ * convenient ways of constructing Timestamps.
+ *
+ * The internal representation of a Timestamp is the two given signed, 32-bit values.
+ * We use 32-bit pieces because these are the size of integers on which
+ * Javascript performs bit-operations. For operations like addition and
+ * multiplication, we split each number into 16-bit pieces, which can easily be
+ * multiplied within Javascript's floating-point representation without overflow
+ * or change in sign.
+ *
+ * In the algorithms below, we frequently reduce the negative case to the
+ * positive case by negating the input(s) and then post-processing the result.
+ * Note that we must ALWAYS check specially whether those values are MIN_VALUE
+ * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
+ * a positive number, it overflows back into a negative). Not handling this
+ * case would often result in infinite recursion.
+ *

+/**
+ * Defines a Long class for representing a 64-bit two's-complement
+ * integer value, which faithfully simulates the behavior of a Java "Long". This
+ * implementation is derived from LongLib in GWT.
+ *
+ * Constructs a 64-bit two's-complement integer, given its low and high 32-bit
+ * values as *signed* integers. See the from* functions below for more
+ * convenient ways of constructing Longs.
+ *
+ * The internal representation of a Long is the two given signed, 32-bit values.
+ * We use 32-bit pieces because these are the size of integers on which
+ * Javascript performs bit-operations. For operations like addition and
+ * multiplication, we split each number into 16-bit pieces, which can easily be
+ * multiplied within Javascript's floating-point representation without overflow
+ * or change in sign.
+ *
+ * In the algorithms below, we frequently reduce the negative case to the
+ * positive case by negating the input(s) and then post-processing the result.
+ * Note that we must ALWAYS check specially whether those values are MIN_VALUE
+ * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
+ * a positive number, it overflows back into a negative). Not handling this
+ * case would often result in infinite recursion.
+ *

+ * @param {number} low the low (signed) 32 bits of the Long.
+ * @param {number} high the high (signed) 32 bits of the Long.

+ * This type is for INTERNAL use in MongoDB only and should not be used in applications.
+ * The appropriate corresponding type is the JavaScript Date type.
+ *
+ * Defines a Timestamp class for representing a 64-bit two's-complement
+ * integer value, which faithfully simulates the behavior of a Java "Timestamp". This
+ * implementation is derived from TimestampLib in GWT.
+ *
+ * Constructs a 64-bit two's-complement integer, given its low and high 32-bit
+ * values as *signed* integers. See the from* functions below for more
+ * convenient ways of constructing Timestamps.
+ *
+ * The internal representation of a Timestamp is the two given signed, 32-bit values.
+ * We use 32-bit pieces because these are the size of integers on which
+ * Javascript performs bit-operations. For operations like addition and
+ * multiplication, we split each number into 16-bit pieces, which can easily be
+ * multiplied within Javascript's floating-point representation without overflow
+ * or change in sign.
+ *
+ * In the algorithms below, we frequently reduce the negative case to the
+ * positive case by negating the input(s) and then post-processing the result.
+ * Note that we must ALWAYS check specially whether those values are MIN_VALUE
+ * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
+ * a positive number, it overflows back into a negative). Not handling this
+ * case would often result in infinite recursion.
