Field Details

logger

protected static final InternalLogger logger

Internal Netty logger.

thread

protected volatile Thread thread

If this worker has been started thread will be a reference to the thread used when starting. i.e. the current thread when the run method is executed.

selector

protected volatile Selector selector

The NIO Selector.

wakenUp

protected final AtomicBoolean wakenUp

Boolean that controls determines if a blocked Selector.select should break out of its selection process. In our case we use a timeone for the select method and the select method will block for that time unless waken up.
