virtual bool Compress ( void* CompressedBuffer,
int64& CompressedSize,
const void* UncompressedBuffer,
int64 UncompressedSize,
uintptr_t CompressionData,
ECompressionFlags Flags
)

 Default 64 bit implementation wraps legacy 32 bit implementation with size checks - will be removed when deprecated function is removed. Misc/ICompressionFormat.h  
Returns whether the compression format internally decides whether the decreased size is worth the CPU cost of decompressing it. Misc/ICompressionFormat.h
