execute

private void execute(PointValueTime newValue)

pointInitialized

public void pointInitialized()

Description copied from interface: DataPointListener

This method is called for all existing listeners when the point is initialized. Note that it is not called for listeners that have begun listening to an already-initialized point.

Specified by:

pointInitialized in interface DataPointListener

pointTerminated

public void pointTerminated()

Description copied from interface: DataPointListener

This method is called when the point has been terminated, allowing listeners to react as necessary.

Specified by:

pointTerminated in interface DataPointListener

pointChanged

public void pointChanged(PointValueTime oldValue,
                         PointValueTime newValue)

Description copied from interface: DataPointListener

This method is called every time the point gets a value that is different from its previous value (except for its initialization). This includes when the point is set, if the set changes the point's value.

Specified by:

pointChanged in interface DataPointListener

pointSet

public void pointSet(PointValueTime oldValue,
                     PointValueTime newValue)

Description copied from interface: DataPointListener

This method is called every time the point gets set, whether the value changes or not.

Specified by:

pointSet in interface DataPointListener

pointBackdated

public void pointBackdated(PointValueTime value)

Description copied from interface: DataPointListener

This method is called when a backdated value is received.

Specified by:

pointBackdated in interface DataPointListener

pointUpdated

public void pointUpdated(PointValueTime newValue)

Description copied from interface: DataPointListener

This method is called every time the point gets a value from somewhere (except for its initialization). This includes when the point changes or is set.

Specified by:

pointUpdated in interface DataPointListener

getSetPointSourceId

public int getSetPointSourceId()

Specified by:

getSetPointSourceId in interface SetPointSource

getSetPointSourceType

public int getSetPointSourceType()

Specified by:

raiseRecursionFailureEvent

public void raiseRecursionFailureEvent()

Specified by:

raiseRecursionFailureEvent in interface SetPointSource

pointSetComplete

public void pointSetComplete()

Specified by:

pointSetComplete in interface PointLinkSetPointSource

Specified by:
