implements EventTrigger

An abstract implementation for an event trigger. Note that this class defines already all methods necessarry for an EventTrigger but is explicetly declared abstract to prevent erroneous instantiation.

Field Detail

sleeper

private Object sleeper

The object to notify of trigger changes.

Constructor Detail

SimpleEventTrigger

public SimpleEventTrigger(Map prop)

Constructs a new abastract event trigger. This instance provides methods for notifying waiting objects whenever its trigger value changes.

Method Detail

setTrigger

public Boolean setTrigger(Boolean val)

Sets the value of this trigger.

Specified by:

setTrigger in interface Trigger

Overrides:

setTrigger in class SimpleTrigger

Returns:

The old value of the trigger.

toggleTrigger

public Boolean toggleTrigger()

Toggles this trigger value.

Specified by:

toggleTrigger in interface Trigger

Overrides:

toggleTrigger in class AbstractTrigger

Returns:

The old value of the trigger.

registerMonitor

public Object registerMonitor(Object waiter)

Registers an object. Event triggers are expected to change their value without prediction. Registering a sequencer guarantees that changes in the trigger value result in a notification of the sequencer.

Specified by:

registerMonitor in interface EventTrigger

getMonitor

protected Object getMonitor()

Returns the object this device trigger notifies. For subclasses that need direct access to the trigger's moitor object.
