Package org.nustaq.offheap.bytez

Interface Bytez

All Superinterfaces:

BasicBytez, ByteSink, ByteSource

All Known Implementing Classes:

HeapBytez, MallocBytez, MemoryBytez, 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 !)

Method Details

slice

Bytez slice(long off,
 int len)

compareAndSwapInt

boolean compareAndSwapInt(long offset,
 int expect,
 int newVal)

compareAndSwapLong

boolean compareAndSwapLong(long offset,
 long expect,
 long newVal)

toBytes

byte[] toBytes(long startIndex,
 int len)

asByteArray

byte[] asByteArray()

Returns:

return the underlying byte array, not supported by MallocBytez !. Use getArr to extract data by copy instead.

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
