Constructor Detail

### SequenceDBWrapper.SequencesForwarder

    public SequenceDBWrapper.SequencesForwarder(Object source,
                                                ChangeSupport cs)

Method Detail

### generateEvent

    public ChangeEvent generateEvent(ChangeEvent ce)

  Description copied from class: `ChangeForwarder`

  Return the new event to represent the originating event ce.

  The returned ChangeEvent is the event that will be fired, and should be built from information in the original event. If it is null, then no event will be fired.

  The default implementation just constructs a ChangeEvent of the same type that chains back to ce.

  Overrides:
    `generateEvent` in class `ChangeForwarder`
  Parameters:
    `ce` - the originating ChangeEvent
  Returns:
    a new ChangeEvent to pass on, or null if no event should be sent
