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.

Protected Methods

Method Description
