Annotation Type ChannelHandler.Skip

@Target(value=METHOD)
@Retention(value=RUNTIME)
public static @interface ChannelHandler.Skip

Indicates that the annotated event handler method in ChannelHandler will not be invoked by ChannelPipeline. This annotation is only useful when your handler method implementation only passes the event through to the next handler, like the following:

 @Skip
 @Override
 public void channelActive(ChannelHandlerContext ctx) {
     ctx.fireChannelActive(); // do nothing but passing through to the next handler
 }
 

ChannelHandler.handlerAdded(ChannelHandlerContext) and ChannelHandler.handlerRemoved(ChannelHandlerContext) are not able to pass the event through to the next handler, so they must do nothing when annotated.

 @Skip
 @Override
 public void handlerAdded(ChannelHandlerContext ctx) {
     // do nothing
 }
 

Note that this annotation is not inherited. If you override a method annotated with ChannelHandler.Skip, it will not be skipped anymore. Similarly, you can override a method not annotated with ChannelHandler.Skip and simply pass the event through to the next handler, which reverses the behavior of the supertype.
