Interface Bytez

All Superinterfaces:

BasicBytez, ByteSource

All Known Implementing Classes:

HeapBytez, MallocBytez, MMFBytez

public interface Bytez
extends BasicBytez

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 !)

asByteArray

byte[] asByteArray()

Returns:

getBAOffsetIndex

int getBAOffsetIndex()

Returns:

the start index inside the byte array returned by asByteArray, not supported by MallocBytez

getBALength

int getBALength()

Returns:

the length inside the byte array returned by asByteArray, not supported by MallocBytez
