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