Interface Bytez

All Superinterfaces:

ByteSource

All Known Implementing Classes:

HeapBytez, MallocBytez, MMFBytez

public interface Bytez
extends ByteSource

abstraction of byte arrays similar to ByteBuffer without the need to create temp objects in order to get long,int,.. views additionally supports volatile read/write (for byte[] based backing buffers only !)
