Метод Описание
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.

UnalignedCopy64() публичный статический Метод

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.
Результат void
