io.netty.buffer

Class ExpandableByteBuf

java.lang.Object

io.netty.buffer.ByteBuf

io.netty.buffer.AbstractByteBuf

io.netty.buffer.ExpandableByteBuf

All Implemented Interfaces:

io.netty.buffer.ByteBufConvertible, io.netty.util.ReferenceCounted, Comparable<io.netty.buffer.ByteBuf>

public class ExpandableByteBuf
extends io.netty.buffer.AbstractByteBuf

Allows us to decorate ArrowBuf to make it expandable so that we can use them in the context of the Netty framework (thus supporting RPC level memory accounting).
