Method Detail

start

public void start()

Description copied from interface: ThreadPooledEventDispatcher

Starts this event dispatcher. this method will silently return if it is already started.

Specified by:

start in interface ThreadPooledEventDispatcher

stop

public void stop()

Description copied from interface: ThreadPooledEventDispatcher

Stops this event dispatcher. This method will silently return if it is already stopped.

Specified by:

stop in interface ThreadPooledEventDispatcher

isStarted

public boolean isStarted()

Description copied from interface: ThreadPooledEventDispatcher

Returns true if this event dispatcher is started.

Specified by:

isStarted in interface ThreadPooledEventDispatcher

getThreadPoolSize

public int getThreadPoolSize()

Description copied from interface: ThreadPooledEventDispatcher

Returns the number of dispatcher threads.

Specified by:

getThreadPoolSize in interface ThreadPooledEventDispatcher

setThreadPoolSize

public void setThreadPoolSize(int newSize)

Description copied from interface: ThreadPooledEventDispatcher

Sets the number of dispatcher threads. This property is adjustable in runtime.

Specified by:

setThreadPoolSize in interface ThreadPooledEventDispatcher

newWorker

protected abstract AbstractThreadPooledEventDispatcher.AbstractWorker newWorker()

removeWorker

protected abstract AbstractThreadPooledEventDispatcher.AbstractWorker removeWorker()

getThreadPriority

public int getThreadPriority()

Description copied from interface: ThreadPooledEventDispatcher

Returns the priority of dispatcher threads.

Specified by:

getThreadPriority in interface ThreadPooledEventDispatcher

setThreadPriority

public void setThreadPriority(int newPriority)

Description copied from interface: ThreadPooledEventDispatcher

Sets the priority of dispatcher threads.

Specified by:

setThreadPriority in interface ThreadPooledEventDispatcher

getThreadNamePrefix

public String getThreadNamePrefix()

Description copied from interface: ThreadPooledEventDispatcher

Returns the prefix of dispatcher thread name.

Specified by:

getThreadNamePrefix in interface ThreadPooledEventDispatcher

setThreadNamePrefix

public void setThreadNamePrefix(String threadNamePrefix)

Description copied from interface: ThreadPooledEventDispatcher

Sets the prefix of dispatcher thread name. This will help you to determine which thread is which when you debug. The actual thread name will be threadNamePrefix + '-' + threadId.

Specified by:

setThreadNamePrefix in interface ThreadPooledEventDispatcher

flush

public void flush()

Description copied from interface: EventDispatcher

(Optional operation) Flushes the buffered events. This method is invoked by ReadController#processEvent(Event)and WriteController#processEvent(Event)after the expected I/O operations have been completed. So you can implement EventDispatcherto buffer the fireXXX calls and fire (flush) them here in actually.

Specified by:

flush in interface EventDispatcher
