PreferHeapByteBufAllocator (Netty 4.1.109.Final API文档

java.lang.Object
- io.netty.channel.PreferHeapByteBufAllocator

所有已实现的接口:

ByteBufAllocator
```
@UnstableApi
public final class PreferHeapByteBufAllocator
extends java.lang.Object
implements ByteBufAllocator
```
Wraps another ByteBufAllocator and use heapbuffers everywhere except when a direct buffer is explicit requested.
