public OnDemandEventLoop(@NotNull
                         @NotNull Supplier<EventLoop> eventLoopSupplier)

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

Stop executing handlers and block until all handlers are complete.

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

Specified by:

stop in interface EventLoop

isClosed

public boolean isClosed()

Description copied from interface: QueryCloseable

Is this object closed

Specified by:

isClosed in interface QueryCloseable

Returns:

true if close() has completed

isAlive

public boolean isAlive()

Specified by:

isAlive in interface EventLoop

Returns:

true if the main thread is running

isStopped

public boolean isStopped()

Specified by:

isStopped in interface EventLoop

Returns:

is it in the stopped state.

awaitTermination

public void awaitTermination()

Description copied from interface: EventLoop

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

Specified by:

awaitTermination in interface EventLoop

close

public void close()

Description copied from interface: EventLoop

Stop the event loop, then close any resources being held.

Blocks until the handlers are all stopped and closed

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface EventLoop
