Public Methods

Method	Description
CalculateCrc ( byte b, int off, int len ) : uint
GetEightBytes ( byte source, int index ) : ulong	> Reads 8 bytes from memory into a uint. Does not take host enianness into account.
GetFourBytes ( byte source, int index ) : uint	> Reads 4 bytes from memory into a uint. Does not take host enianness into account.
Log2Floor ( uint x ) : uint
NativeIntPtrSize ( ) : int
NumberOfLeadingZeros ( uint x ) : uint
NumberOfOnes ( uint x ) : uint
NumberOfTrailingZeros ( uint x ) : uint
NumberOfTrailingZeros ( ulong c ) : uint
UnalignedCopy64 ( byte source, int sourceIndex, byte dest, int destIndex ) : void	Copies 64 bits (8 bytes) from source array starting at sourceIndex into dest array starting at destIndex. The name comes from the original Snappy C++ source. I don't think there is a good way to look at things in an aligned manner in the .NET Framework.

public static UnalignedCopy64 ( byte source, int sourceIndex, byte dest, int destIndex ) : void
source	byte	The source array.
sourceIndex	int	Index to start copying.
dest	byte	The destination array.
destIndex	int	Index to start writing.
return	void
