Method Detail

hasEventLoop

public boolean hasEventLoop()

name

public String name()

Specified by:

name in interface EventLoop

addHandler

public void addHandler(EventHandler handler)

Description copied from interface: EventLoop

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 EventLoop.start() has been called.

Specified by:

addHandler in interface EventLoop

Parameters:

handler - handler

start

public void start()

Description copied from interface: EventLoop

Start the event loop

Specified by:

start in interface EventLoop

unpause

public void unpause()

Description copied from interface: EventLoop

Typical implementation will unpause the event loop's Pauser

Specified by:

unpause in interface EventLoop

stop

public void stop()

Description copied from interface: EventLoop

Notify event loop to stop executing handlers. It is not expected that event loops can then be restarted

Specified by:

stop in interface EventLoop

isClosed

public boolean isClosed()

Specified by:

isClosed in interface QueryCloseable

Specified by:

isClosed in interface EventLoop

Returns:

true close has been called

isAlive

public boolean isAlive()

Specified by:

isAlive in interface EventLoop

Returns:

true if the main thread is running

awaitTermination

public void awaitTermination()

Description copied from interface: EventLoop

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

Specified by:

awaitTermination in interface EventLoop

close

public void close()

Description copied from interface: Closeable

Doesn't throw a checked exception.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable
