ArrowByteBufAllocator (Arrow Memory 0.8.0 API)

java.lang.Object
- io.netty.buffer.AbstractByteBufAllocator
- - org.apache.arrow.memory.ArrowByteBufAllocator

All Implemented Interfaces:

io.netty.buffer.ByteBufAllocator
```
public class ArrowByteBufAllocator
extends io.netty.buffer.AbstractByteBufAllocator
```
An implementation of ByteBufAllocator that wraps a Arrow BufferAllocator. This allows the RPC layer to be accounted and managed using Arrow's BufferAllocator infrastructure. The only thin different from a typical BufferAllocator is the signature and the fact that this Allocator returns ExpandableByteBufs which enable otherwise non-expandable ArrowBufs to be expandable.
