Public Methods

Method	Description
Clear ( ) : void	Clears this instance.
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
FindNullByte ( ) : int	Finds the next null byte.
GetSlice ( int position, int length ) : IByteBuffer	Gets a slice of this buffer.
LoadFrom ( Stream stream, int count ) : void	Loads the buffer from a stream.
MakeReadOnly ( ) : void	Makes this buffer read only.
MultiChunkBuffer ( MongoDB.Bson.IO.BsonChunkPool chunkPool ) : System	Initializes a new instance of the MultiChunkBuffer class.
ReadBackingBytes ( int count ) : ArraySegment	Read directly from the backing bytes. The returned ArraySegment points directly to the backing bytes for the current position and you can read the bytes directly from there. If the backing bytes happen to span a chunk boundary shortly after the current position there might not be enough bytes left in the current chunk in which case the returned ArraySegment will have a Count of zero and you should call ReadBytes instead. When ReadBackingBytes returns the position will have been advanced by count bytes if and only if there were count bytes left in the current chunk.
ReadByte ( ) : byte	Reads a byte.
ReadBytes ( int count ) : byte[]	Reads bytes.
ReadBytes ( byte destination, int destinationOffset, int count ) : void	Reads bytes.
WriteBackingBytes ( int count ) : ArraySegment	Write directly to the backing bytes. The returned ArraySegment points directly to the backing bytes for the current position and you can write the bytes directly to there. If the backing bytes happen to span a chunk boundary shortly after the current position there might not be enough bytes left in the current chunk in which case the returned ArraySegment will have a Count of zero and you should call WriteBytes instead. When WriteBackingBytes returns the position has not been advanced. After you have written up to count bytes directly to the backing bytes advance the position by the number of bytes actually written.
WriteByte ( byte source ) : void	Writes a byte.
WriteBytes ( IByteBuffer source ) : void	Writes bytes.
WriteBytes ( byte source ) : void	Writes bytes.
WriteTo ( Stream stream ) : void	Writes Length bytes from this buffer starting at Position 0 to a stream.

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public Dispose ( ) : void
return	void

Dispose() protected method

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

GetSlice() public method

Gets a slice of this buffer.

MultiChunkBuffer GetSlice can only be called for read only buffers. /// position /// or /// length ///

public GetSlice ( int position, int length ) : IByteBuffer
position	int	The position of the start of the slice.
length	int	The length of the slice.
return	IByteBuffer

LoadFrom() public method

Loads the buffer from a stream.

MultiChunkBuffer The MultiChunkBuffer is read only. stream count

public LoadFrom ( Stream stream, int count ) : void
stream	Stream	The stream.
count	int	The count.
return	void

MakeReadOnly() public method

Initializes a new instance of the MultiChunkBuffer class.

chunkPool

public MultiChunkBuffer ( MongoDB.Bson.IO.BsonChunkPool chunkPool ) : System
chunkPool	MongoDB.Bson.IO.BsonChunkPool	The chunk pool.
return	System

ReadBackingBytes() public method

Read directly from the backing bytes. The returned ArraySegment points directly to the backing bytes for the current position and you can read the bytes directly from there. If the backing bytes happen to span a chunk boundary shortly after the current position there might not be enough bytes left in the current chunk in which case the returned ArraySegment will have a Count of zero and you should call ReadBytes instead. When ReadBackingBytes returns the position will have been advanced by count bytes *if and only if* there were count bytes left in the current chunk.

public ReadBackingBytes ( int count ) : ArraySegment
count	int	The number of bytes you need to read.
return	ArraySegment

ReadByte() public method

Reads a byte.

destinationOffset	int	The destination offset.
count	int	The count.
return	void

ThrowIfDisposed() protected method

Throws if disposed.

protected ThrowIfDisposed ( ) : void
return	void

WriteBackingBytes() public method

Write directly to the backing bytes. The returned ArraySegment points directly to the backing bytes for the current position and you can write the bytes directly to there. If the backing bytes happen to span a chunk boundary shortly after the current position there might not be enough bytes left in the current chunk in which case the returned ArraySegment will have a Count of zero and you should call WriteBytes instead. When WriteBackingBytes returns the position has not been advanced. After you have written up to count bytes directly to the backing bytes advance the position by the number of bytes actually written.
