public class ChannelInboundHandlerAdapter
extends ChannelHandlerAdapter
implements ChannelInboundHandler

Abstract base class for ChannelInboundHandler implementations which provide implementations of all of their methods.

This implementation just forward the operation to the next ChannelHandler in the ChannelPipeline. Sub-classes may override a method implementation to change this.

Be aware that messages are not released after the channelRead(ChannelHandlerContext, Object) method returns automatically. If you are looking for a ChannelInboundHandler implementation that releases the received messages automatically, please see SimpleChannelInboundHandler.
