toString

public String toString()

Gets a string representation

Overrides:

toString in class Object

Returns:

A string representation

fire

public void fire(T event)

Description copied from interface: Event

Fires an event with the specified qualifiers and notifies observers.

Specified by:

fire in interface Event<T>

Parameters:

event - the event object

fireAsync

public <U extends T> CompletionStage<U> fireAsync(U event)

Description copied from interface: Event

Fires an event asynchronously with the specified qualifiers and notifies asynchronous observers.

Specified by:

fireAsync in interface Event<T>

Type Parameters:

U - event type

Parameters:

event - the event object

Returns:

a CompletionStage allowing further pipeline composition on the asynchronous operation. Default asynchronous execution facility is container specific. If any observer notified by this event throws an exception then the resulting CompletionStage is completed exceptionally with CompletionException that wraps all the exceptions raised by observers as suppressed exception. If no exception is thrown by observers then the resulting CompletionStage is completed normally with the event payload.

fireAsync

public <U extends T> CompletionStage<U> fireAsync(U event,
                                                  NotificationOptions options)

Description copied from interface: Event

Fires an event asynchronously with the specified qualifiers and notifies asynchronous observers. A custom Executor will be used to make asynchronous calls

Specified by:

fireAsync in interface Event<T>

Type Parameters:

U - event type

Parameters:

event - the event object

options - the notification options

Returns:

a CompletionStage allowing further pipeline composition on the asynchronous operation. Default asynchronous execution facility is container specific. If any observer notified by this event throws an exception then the resulting CompletionStage is completed exceptionally with CompletionException that wraps all the exceptions raised by observers as suppressed exception. If no exception is thrown by observers then the resulting CompletionStage is completed normally with the event payload.

select

public WeldEvent<T> select(Annotation... qualifiers)

Description copied from interface: Event

Parameters:

select

public <U extends T> WeldEvent<U> select(Class<U> subtype,
                                         Annotation... qualifiers)

Description copied from interface: Event

Obtains a child Event for the given required type and additional required qualifiers.

Specified by:

select in interface Event<T>

Specified by:

select in interface WeldEvent<T>

Type Parameters:

                                         Annotation... qualifiers)

Description copied from interface: Event

Obtains a child Event for the given required type and additional required qualifiers.

Specified by:

select in interface Event<T>

Specified by:

select in interface WeldEvent<T>

Type Parameters:

U - the specified type

Parameters:

subtype - a TypeLiteral representing the specified type

qualifiers - the additional specified qualifiers

                               Annotation... qualifiers)

Description copied from interface: WeldEvent

Specified by:

select in interface WeldEvent<T>

Type Parameters:

X - the required type

Parameters:

type - a Type representing the required type

qualifiers - the additional required qualifiers

Returns:

the child Event

getEventType
