public abstract class AbstractComponent
extends java.lang.Object
implements Component

Provides some common implementation that useful to all that interact with RegisteringEventEmitters components, including:

• Maintaining a reference to an EventEmitter
• Wraps incoming EventEmitter in a RegisteringEventEmitter
• Ensures incoming EventEmitter is not null
• Maintains a collection of EventListener tokens for use with EventEmitter.off()
• Provides standard required method for initializing Event listeners

AbstractComponent

public AbstractComponent(EventEmitter eventEmitter,
                         java.lang.Class<? extends Component> componentClass)

Being Components, Controllers inheriting from AbstractController require an EventEmitter on initialization.

Parameters:

eventEmitter - the EventEmitter through which this Component will listen for and emit events to interact with other components in the player

AbstractComponent

public AbstractComponent(EventEmitter eventEmitter)

Build an AbstractComponent that does not use a registering event emitter.

Parameters:

eventEmitter - the EventEmitter through which this Component will listen for and emit events to interact with other components in the player

Method Detail

addListener

public void addListener(java.lang.String eventType,
                        EventListener listener)

Convenience method to add an EventListener for the given type using the EventEmitter.on() method.

Parameters:

eventType - the EventType for which the listener should be called

listener - the implementation of EventListener for this EventType

addOnceListener

public void addOnceListener(java.lang.String eventType,
                            EventListener listener)

Convenience method to add an EventListener for the given type using the EventEmitter.once() method.

Parameters:

eventType - the EventType for which the listener should be called

listener - the implementation of EventListener for this EventType

removeListener

public void removeListener(java.lang.String eventType)

Removes the specified listener from the EventEmitter.

Parameters:

eventType - the EventType for which the listener should be called

removeListeners

public void removeListeners()

Removes all set listeners from the EventEmitter.

getEventEmitter

public EventEmitter getEventEmitter()

Provides a reference to the EventEmitter with which this component was initialized

Returns:

the EventEmitter used by this Component
