Method Detail

name

String name()

addHandler

void addHandler(EventHandler handler)

Add handler to event loop to be executed. Event loops should execute handlers in order of priority. Handlers with same priority have no guarantee of execution order. Handlers will not be executed before start() has been called.

Parameters:

handler - handler

start

void start()

Start the event loop

unpause

void unpause()

Typical implementation will unpause the event loop's Pauser

stop

void stop()

Stop executing handlers and block until all handlers are complete.

It is not expected that event loops can then be restarted.

isAlive

boolean isAlive()

Returns:

true if the main thread is running

isStopped

boolean isStopped()

Returns:

is it in the stopped state.

awaitTermination

void awaitTermination()

Wait until the event loop has terminated (after stop() has been called)

inEventLoop

static boolean inEventLoop()

Returns:

true if called in an EventLoop.

close

void close()

Stop the event loop, then close any resources being held. Blocks until the handlers are all stopped and closed
