## org.quartz.listeners
Class SchedulerListenerSupport

    java.lang.Object
      org.quartz.listeners.SchedulerListenerSupport

All Implemented Interfaces:
  SchedulerListener

Direct Known Subclasses:
  JobRunShell, QuartzServer, SampledStatisticsImpl

    public abstract class SchedulerListenerSupport

extends Object
implements SchedulerListener

A helpful abstract base class for implementors of ``SchedulerListener``.

The methods in this class are empty so you only need to override the subset for the ``SchedulerListener`` events you care about.

  `SchedulerListener`

Constructor Summary
`SchedulerListenerSupport()`

    `triggerFinalized` in interface `SchedulerListener`

### triggersPaused

    public void triggersPaused(String triggerName,
                               String triggerGroup)

  Description copied from interface: `SchedulerListener`

  Specified by:
    `triggersPaused` in interface `SchedulerListener`

### triggersResumed

  Called by the ``Scheduler`` when a serious error has occurred within the scheduler - such as repeated failures in the `JobStore`, or the inability to instantiate a `Job` instance when its `Trigger` has fired.

  The `getErrorCode()` method of the given SchedulerException can be used to determine more specific information about the type of error that was encountered.

  Specified by:
    `schedulerError` in interface `SchedulerListener`
