TODO: Javadoc

Returns:

events

public final rcf.core.util.collection.ImmutableCollection<Class> events()

Description copied from interface: EventSource

Return an immutable collection of all the classes of Events which this source will generate and syndicate. This can be used to check if a source will be will to generate specific events of interest to a potential sink.

Specified by:

events in interface EventSource

Returns:

An immutable collection of all the classes of events which this source will generate and syndicate.

taskState

public Task.State taskState()

Description copied from interface: Task

TODO: Javadoc

Specified by:

taskState in interface Task

Returns:

taskState

protected Task.State taskState(Task.State _state)

TODO: Javadoc

Parameters:

_state -

syndicate

public EventSyndicate syndicate()

Description copied from interface: EventSource

Return the current syndicate for this event source, or allocate one if there isn't one. This method should never return null unless EventSource.events().ImmutableIterable.isEmpty() == true.

Specified by:

syndicate in interface EventSource

Overrides:

syndicate in class AbstractEventSource

Returns:

The event syndicate which an EventSink should register with (EventSyndicate.add(rcf.core.util.reference.Reference, Class)) to receive events from this source.
