Class HeapByteBufAllocator

java.lang.Object

org.apache.hbase.thirdparty.io.netty.buffer.AbstractByteBufAllocator

org.apache.hadoop.hbase.ipc.HeapByteBufAllocator

All Implemented Interfaces:

org.apache.hbase.thirdparty.io.netty.buffer.ByteBufAllocator

@InterfaceAudience.Private
public class HeapByteBufAllocator
extends org.apache.hbase.thirdparty.io.netty.buffer.AbstractByteBufAllocator

A pooled ByteBufAllocator that does not prefer direct buffers regardless of platform settings.

In some cases direct buffers are still required, like IO buffers where the buffer will be used in conjunction with a native method call, so we cannot force all buffer usage on heap. But we can strongly prefer it.
