Method Summary

Modifier and Type	Method and Description
void	pointBackdated(PointValueTime value) This method is called when a backdated value is received.
void	pointChanged(PointValueTime oldValue, PointValueTime newValue) This method is called every time the point gets a value that is different from its previous value (except for its initialization).
void	pointInitialized() This method is called for all existing listeners when the point is initialized.
void	pointSet(PointValueTime oldValue, PointValueTime newValue) This method is called every time the point gets set, whether the value changes or not.
void	pointTerminated() This method is called when the point has been terminated, allowing listeners to react as necessary.
void	pointUpdated(PointValueTime newValue) This method is called every time the point gets a value from somewhere (except for its initialization).

Method Detail

pointInitialized

void pointInitialized()

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.

pointUpdated

void pointUpdated(PointValueTime newValue)

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.

Parameters:

newValue -

pointChanged

void pointChanged(PointValueTime oldValue,
                  PointValueTime newValue)

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.

Parameters:

oldValue -

newValue -

pointSet

void pointSet(PointValueTime oldValue,
              PointValueTime newValue)

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

Parameters:

oldValue -

newValue -

pointBackdated

void pointBackdated(PointValueTime value)

This method is called when a backdated value is received.

Parameters:

value -

pointTerminated

void pointTerminated()

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