C# Класс SharpGIS.ZLib.CRC32

Calculates a 32bit Cyclic Redundancy Checksum (CRC) using the same polynomial used by Zip. This type is used internally by DotNetZip; it is generally not used directly by applications wishing to create, read, or manipulate zip archive files.

Метод	Описание
ComputeCrc32 ( Int32 W, byte B ) : Int32	Get the CRC32 for the given (word,byte) combo. This is a computation defined by PKzip.
GetCrc32 ( System input ) : Int32	Returns the CRC32 for the specified stream.
GetCrc32AndCopy ( System input, System output ) : Int32	Returns the CRC32 for the specified stream, and writes the input into the output stream.
SlurpBlock ( byte block, int offset, int count ) : void	Update the value for the running CRC32 using the given block of bytes. This is useful when using the CRC32() class in a Stream.

Описание методов

ComputeCrc32() публичный Метод

Get the CRC32 for the given (word,byte) combo. This is a computation defined by PKzip.

public ComputeCrc32 ( Int32 W, byte B ) : Int32
W	System.Int32	The word to start with.
B	byte	The byte to combine it with.
Результат	System.Int32

GetCrc32() публичный Метод

Returns the CRC32 for the specified stream.

public GetCrc32 ( System input ) : Int32
input	System	The stream over which to calculate the CRC32
Результат	System.Int32

GetCrc32AndCopy() публичный Метод

Returns the CRC32 for the specified stream, and writes the input into the output stream.

public GetCrc32AndCopy ( System input, System output ) : Int32
input	System	The stream over which to calculate the CRC32
output	System	The stream into which to deflate the input
Результат	System.Int32

SlurpBlock() публичный Метод

Update the value for the running CRC32 using the given block of bytes. This is useful when using the CRC32() class in a Stream.

public SlurpBlock ( byte block, int offset, int count ) : void
block	byte	block of bytes to slurp
offset	int	starting point in the block
count	int	how many bytes within the block to slurp
Результат	void
