send

public <T extends ActionObject> void send(ActionId<T> type,
                                          T arg)

Specified by:

send in interface ViewEngine

send

public void send(ActionId<EmptyAction> type)

Specified by:

send in interface ViewEngine

request

public <V,T> void request(ActionId<RequestAction<V,T>> type,
                          V requestParameter,
                          ResponseCallback<T> callback)

Specified by:

request

public <T> void request(ActionId<RequestAction<java.lang.Void,T>> type,
                        ResponseCallback<T> callback)

Specified by:

fireEvent

public <T extends EventObject> void fireEvent(EventId<T> eventType,
                                              T argument)

Description copied from interface: ControlEngine

Fires the event with an argument passed to listeners.

Specified by:

fireEvent in interface ControlEngine

Type Parameters:

T - The type of the argument, it must extend the EventObject class.

Parameters:

eventType - The id of the event

argument - The argument of matching T type that will be passed to event listeners

fireEvent

public void fireEvent(EventId<EmptyEvent> type)

Description copied from interface: ControlEngine

Fires an event and allows all event listeners to handle it.
This is a convenience method that fires an emptyEvent so eventListeners does not need the event argument.

Specified by:

fireEvent in interface ControlEngine

Parameters:

type - The id of the event (must be an EmptyEvent)

get

public <T> T get(ModelId<T> type)

Description copied from interface: ControlEngine

Gets a value from the engine model repository.

Specified by:

get in interface ControlEngine

Specified by:

get in interface ViewEngine

Type Parameters:

T - The type of the value stored

Parameters:

type - the id of the model variable stored in the engine

Returns:

the model variable value or null if none is found

set

public <T> void set(ModelId<T> type,
                    T value,
                    EventId<ValueEvent<T>> event)

Specified by:

set in interface ControlEngine

addActionHandler
