Observer for consuming events.

  • Field Summary

    Fields
    Modifier and Type
    Field
    Description
    static final int
    MAX_PRIORITY
    Maximum priority.
    static final int
    MIN_PRIORITY
    Minimum priority.

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    getPriority(Event event)
    Retrieves the priority to observe this event.
    This can be used to process a supported event before others observers.
    void
    observe(Event event, Map<String,Object> transientVars)
    Observes an event.
    boolean
    supports(Event event)
    Checks if the event is supported.

  • Method Details

    • supports

      boolean supports(Event event)
      Checks if the event is supported. If true, the observe(Event) method will be called.
      Parameters:
      event - the event.
      Returns:
      true for observing this event, false otherwise.

    • getPriority

      int getPriority(Event event)
      Retrieves the priority to observe this event.
      This can be used to process a supported event before others observers.
      Parameters:
      event - the event.
      Returns:
      the priority where 0 the max priority and Integer.MAX_VALUE the min priority.

    • observe

      void observe(Event event, Map<String,Object> transientVars) throws Exception
      Observes an event.
      Parameters:
      event - the event.
      transientVars - transientVars passed from one Observer to another when processing a single Event. This may allow optimizations between observers.
      Throws:
      Exception - if an error occurs. All exceptions will be logged but not propagated, as the observation mechanism should never fail.
