Class Summary
Class	Description
BsonInputStream	`BsonInputStream` provides a class to read BSON documents based on the BSON specification.
BsonOutputStream	A wrapper for an `OutputStream` to handle writing BSON primitives.
BufferingBsonOutputStream	`BufferingBsonOutputStream` provides a class to write BSON documents based on the BSON specification.
EndianUtils	Utilities to deal with integer endian differences.
RandomAccessOutputStream	Provides a capability similar to the `ByteArrayOutputStream` but also provides the ability to re-write portions of the stream already written and to determine the current size (or position) of the written data.
SizeOfVisitor	A visitor to determine the size of the documents it visits.
SizeOfVisitor.CachedSizeNode	CachedSizeNode provides a node in a singly linked list that forms the cache for the sizes of lists of elements.

Package com.allanbank.mongodb.bson.io Description

Provides the ability to serialize and deserialize BSON Documents.

Two implementations of stream are provided:

BsonInputStream/BsonOutputStream provide the ability to read and write BSON documents directly to a stream without the need to buffer document contents to determine the length prefix for the document. They require 2 scans over the document. The first determines the size of the document and the second writes the document's contents.
BufferingBsonOutputStream provide the ability to write BSON documents using an intermediate re-used set of buffers for the document's contents.

Empirical testing has shown that the un-buffered BsonInputStream and BsonOutputStream perform better on most BSON documents.
