Public Methods

Method	Description
CRC32 ( ) : System	Construct an instance of the CRC32 class, pre-initialising the table for speed of lookup.
GetCrc32 ( System input ) : UInt32	Returns the CRC32 for the specified stream.
GetCrc32AndCopy ( System input, System output ) : UInt32	Returns the CRC32 for the specified stream, and writes the input into the output stream.
