EventListenerGroupImpl

public EventListenerGroupImpl(EventType<T> eventType)

Method Detail

getEventType

public EventType<T> getEventType()

Description copied from interface: EventListenerGroup

Retrieve the event type associated with this groups of listeners.

Specified by:

getEventType in interface EventListenerGroup<T>

Returns:

The event type.

isEmpty

public boolean isEmpty()

Description copied from interface: EventListenerGroup

Are there no listeners registered?

Specified by:

isEmpty in interface EventListenerGroup<T>

Returns:

true if no listeners are registered; false otherwise.

count

public int count()

Specified by:

count in interface EventListenerGroup<T>

clear

public void clear()

Specified by:

clear in interface EventListenerGroup<T>

addDuplicationStrategy

public void addDuplicationStrategy(DuplicationStrategy strategy)

Description copied from interface: EventListenerGroup

Mechanism to more finely control the notion of duplicates.

For example, say you are registering listeners for an extension library. This extension library could define a "marker interface" which indicates listeners related to it and register a strategy that checks against that marker interface.

Specified by:

addDuplicationStrategy in interface EventListenerGroup<T>

Parameters:

strategy - The duplication strategy

listeners

public Iterable<T> listeners()

Specified by:

listeners in interface EventListenerGroup<T>

appendListeners

public void appendListeners(T... listeners)

Specified by:

appendListeners in interface EventListenerGroup<T>

appendListener

public void appendListener(T listener)

Specified by:

appendListener in interface EventListenerGroup<T>

prependListeners

public void prependListeners(T... listeners)

Specified by:

prependListeners in interface EventListenerGroup<T>

prependListener

public void prependListener(T listener)

Specified by:

prependListener in interface EventListenerGroup<T>
