## org.jboss.netty.channel
Interface LifeCycleAwareChannelHandler

All Superinterfaces:
  ChannelHandler

All Known Implementing Classes:
  IdleStateHandler, ReadTimeoutHandler, SslHandler, ZlibEncoder

    public interface LifeCycleAwareChannelHandler

extends ChannelHandler

A `ChannelHandler` that is notified when it is added to or removed from a `ChannelPipeline`.

### Invalid access to the `ChannelHandlerContext`

Calling `ChannelHandlerContext.sendUpstream(ChannelEvent)` or `ChannelHandlerContext.sendDownstream(ChannelEvent)` in `beforeAdd(ChannelHandlerContext)` or `afterRemove(ChannelHandlerContext)` might lead to an unexpected behavior. It is because the context object might not have been fully added to the pipeline or the context object is not a part of the pipeline anymore respectively.
