How to use

IdleStateHandler$ReaderIdleTimeoutTask

in

org.jboss.netty.handler.timeout

private void initialize(ChannelHandlerContext ctx) {
  State state = state(ctx);
  // Avoid the case where destroy() is called before scheduling timeouts.
  // See: https://github.com/netty/netty/issues/143
  synchronized (state) {
    switch (state.state) {
    case 1:
    case 2:
      return;
    }
    state.state = 1;
  }
  state.lastReadTime = state.lastWriteTime = System.currentTimeMillis();
  if (readerIdleTimeMillis > 0) {
    state.readerIdleTimeout = timer.newTimeout(
        new ReaderIdleTimeoutTask(ctx),
        readerIdleTimeMillis, TimeUnit.MILLISECONDS);
  }
  if (writerIdleTimeMillis > 0) {
    state.writerIdleTimeout = timer.newTimeout(
        new WriterIdleTimeoutTask(ctx),
        writerIdleTimeMillis, TimeUnit.MILLISECONDS);
  }
  if (allIdleTimeMillis > 0) {
    state.allIdleTimeout = timer.newTimeout(
        new AllIdleTimeoutTask(ctx),
        allIdleTimeMillis, TimeUnit.MILLISECONDS);
  }
}
