Public Methods

Method	Description
ComputeChunkedContentLength ( long originalLength ) : long	Computes the total size of the data payload, including the chunk metadata. Called externally so as to be able to set the correct Content-Length header value.
Read ( byte buffer, int offset, int count ) : int	Reads some or all of the processed chunk to the consumer, constructing and streaming a new chunk if more input data is available.

Private Methods

Method	Description
CalculateChunkHeaderLength ( long chunkDataSize ) : long	Computes the size of the header data for each chunk.
ChunkedUploadWrapperStream ( Stream stream, int wrappedStreamBufferSize, AWS4SigningResult headerSigningResult ) : System
ConstructOutputBufferChunk ( int dataLen ) : void	Computes the derived signature for a chunk of data of given length in the input buffer, placing a formatted chunk with headers, signature and data into the output buffer ready for streaming back to the consumer.
FillInputBuffer ( ) : int	Attempt to read sufficient data for a whole chunk from the wrapped stream, returning the number of bytes successfully read to be processed into a chunk
