Method Detail

dispatch

public void dispatch(boolean ignoreVersion,
                     boolean allowNotFound,
                     OperationResult result)
              throws SchemaException

Description copied from interface: SystemConfigurationChangeDispatcher

Dispatches information on system configuration object change. Basically this directly pushes information to lower layers (prism, schema, repo, etc), and calls registered listeners that originate in upper layers.

Specified by:

dispatch in interface SystemConfigurationChangeDispatcher

Parameters:

ignoreVersion - If false, the information is dispatched unconditionally. If true, we dispatch the notification only if the system configuration version was really changed. This is to easily support sources that "ping" sysconfig object in regular intervals, e.g. the cluster manager thread.

allowNotFound - If true, we take non-existence of sysconfig object more easily. To be used e.g. on system init or during tests execution.

Throws:

SchemaException

registerListener

public void registerListener(SystemConfigurationChangeListener listener)

Description copied from interface: SystemConfigurationChangeDispatcher

Specified by:

unregisterListener

public void unregisterListener(SystemConfigurationChangeListener listener)

Description copied from interface: SystemConfigurationChangeDispatcher

Unregisters a listener.

Specified by:

unregisterListener in interface SystemConfigurationChangeDispatcher
