Public Methods

Method	Description
Allocate ( ) : byte[]	Allocates a chunk of memory. If memory is cached it is returned. If no memory is cached then it is allocated. Check the size of the returned buffer to determine how much memory was allocated.
Free ( byte data ) : void	Frees an unused buffer. This may be added to the cache.
MemoryCache ( int bufferSize, int maxCachedBuffers ) : System	Initializes a new instance of the MemoryCache class.

Private Methods

Method	Description
GetStartingOffset ( ) : int	Get the offset in the cached buffers array to start allocating or freeing buffers to. This is done so that all threads don't start operating on slot zero, which would increase contention.
