C# Class ICSharpCode.SharpZipLib.Zip.Compression.Streams.OutputWindow

Contains the output from the Inflation process. We need to have a window so that we can refer backwards into the output stream to repeat stuff.

Public Methods

Method	Description
CopyDict ( byte dictionary, int offset, int length ) : void	Copy dictionary to window
CopyOutput ( byte output, int offset, int len ) : int	Copy contents of window to output
CopyStored ( StreamManipulator input, int length ) : int	Copy from input manipulator to internal window
GetAvailable ( ) : int	Get bytes available for output in window
GetFreeSpace ( ) : int	Get remaining unfilled space in window
Repeat ( int length, int distance ) : void	Append a byte pattern already in the window itself
Reset ( ) : void	Reset by clearing window so GetAvailable returns 0
