• getPhaseId

  public PhaseId getPhaseId()

  Return the identifier of the request processing phase during which this event should be delivered. Legal values are the singleton instances defined by the PhaseId class, including PhaseId.ANY_PHASE, which is the default value.

  Returns:

  the phase id.
