Examples of io.netty.util.concurrent.EventExecutor

io.netty.util.concurrent.EventExecutor
The {@link EventExecutor} is a special {@link ScheduledExecutorService} which comeswith some handy methods to see if a {@link Thread} is executed in a event loop.Beside this it also extends the {@link EventExecutorGroup} to allow a generic way toaccess methods.
