Method Details

addEventInterceptor

<E extends Event<? extends Enum>> void addEventInterceptor(EventInterceptor<E> interceptor)

Add an EventInterceptor to this dispatcher to be used to process Events. The EventInterceptor will be analyzed to determine applicability to this dispatcher and an identifier will be generated if not specified via an annotation. The generated identifier is the fully qualified class name.

Type Parameters:

E - the Event the interceptor accepts

Parameters:

interceptor - the EventInterceptor to add

addEventInterceptor

<E extends Event<? extends Enum>> void addEventInterceptor(String sIdentifier,
 EventInterceptor<E> interceptor)

Add a uniquely identified EventInterceptor to this dispatcher to be used to process Events. The EventInterceptor will be analyzed to determine applicability to this dispatcher.

Type Parameters:

E - the Event the interceptor accepts

Parameters:

sIdentifier - the unique name of the EventInterceptor to add

interceptor - the EventInterceptor to add

addEventInterceptor

<T extends Enum<T>,
E extends Event<T>> void addEventInterceptor(String sIdentifier,
 EventInterceptor<E> interceptor,
 Set<T> setTypes,
 boolean fFirst)

Add a uniquely identified EventInterceptor to this dispatcher to be used to process Events.

Type Parameters:

T - the type of events dispatched by Event EventDispatcher

E - the Event the interceptor accepts

Parameters:

sIdentifier - the unique name of the EventInterceptor to add

interceptor - the EventInterceptor to add

setTypes - the Event types the specified interceptor is subscribing to, or null to subscribe to all events

fFirst - true iff the EventInterceptor should be added to the head of this dispatcher's interceptor chain

removeEventInterceptor

<E extends Event<? extends Enum>> void removeEventInterceptor(EventInterceptor<E> interceptor)

Remove an EventInterceptor from this dispatcher.

Type Parameters:

E - the Event the interceptor accepts

Parameters:

interceptor - the EventInterceptor to be removed from the dispatcher based on identity reference

removeEventInterceptor

<E extends Event<? extends Enum>> void removeEventInterceptor(String sIdentifier)

Remove an EventInterceptor from this dispatcher.

Parameters:

sIdentifier - the unique name identifying the EventInterceptor to remove

getSupportedTypes

Set<Enum> getSupportedTypes()

Return the set of Event types this EventDispatcher supports.

Returns:

the set of Event types this EventDispatcher supports
