Package org.nustaq.offheap.bytez.onheap

Class HeapBytez

java.lang.Object
org.nustaq.offheap.bytez.onheap.HeapBytez
All Implemented Interfaces:
BasicBytez, ByteSink, ByteSource, Bytez, VolatileByteAccess
public class HeapBytez extends Object implements Bytez, VolatileByteAccess
byte array abstraction based on heap byte arrays. FIXME: Should be moved to ordinary safe access as it really seems not to make a big difference.
