Constructor Detail

### MapperListener

    public MapperListener(Mapper mapper,
                          Connector connector)

  Create mapper listener.

Method Detail

### getConnectorName

    @Deprecated
    public String getConnectorName()

  Deprecated.

### startInternal

    public void startInternal()
                       throws LifecycleException

  Description copied from class: `LifecycleBase`
  Sub-classes must ensure that the state is changed to `LifecycleState.STARTING` during the execution of this method. Changing state will trigger the `Lifecycle.START_EVENT` event. If a component fails to start it may either throw a `LifecycleException` which will cause it's parent to fail to start or it can place itself in the error state in which case `LifecycleBase.stop()` will be called on the failed component but the parent component will continue to start normally.

  Specified by:
    `startInternal` in class `LifecycleBase`
  Throws:
    `LifecycleException`

### stopInternal

    public void stopInternal()
                      throws LifecycleException

  Description copied from class: `LifecycleBase`
  Sub-classes must ensure that the state is changed to `LifecycleState.STOPPING` during the execution of this method. Changing state will trigger the `Lifecycle.STOP_EVENT` event.

  Specified by:
    `stopInternal` in class `LifecycleBase`
  Throws:
    `LifecycleException`

### getDomainInternal

    protected String getDomainInternal()

  Description copied from class: `LifecycleMBeanBase`
  Method implemented by sub-classes to identify the domain in which MBeans should be registered.

  Specified by:
    `getDomainInternal` in class `LifecycleMBeanBase`
  Returns:
    The name of the domain to use to register MBeans.

### getObjectNameKeyProperties

    protected String getObjectNameKeyProperties()

  Description copied from class: `LifecycleMBeanBase`
  Allow sub-classes to specify the key properties component of the `ObjectName` that will be used to register this component.

  Specified by:
    `getObjectNameKeyProperties` in class `LifecycleMBeanBase`
  Returns:
    The string representation of the key properties component of the desired `ObjectName`

### containerEvent

    public void containerEvent(ContainerEvent event)

  Description copied from interface: `ContainerListener`
  Acknowledge the occurrence of the specified event.

  Specified by:
    `containerEvent` in interface `ContainerListener`
  Parameters:
    `event` - ContainerEvent that has occurred

### lifecycleEvent

    public void lifecycleEvent(LifecycleEvent event)

  Description copied from interface: `LifecycleListener`
  Acknowledge the occurrence of the specified event.

  Specified by:
    `lifecycleEvent` in interface `LifecycleListener`
  Parameters:
    `event` - LifecycleEvent that has occurred
