Class DefaultPropertyBackedBeanRegistry

java.lang.Object

org.alfresco.repo.management.subsystems.DefaultPropertyBackedBeanRegistry

All Implemented Interfaces:

EventListener, PropertyBackedBeanRegistry, TransactionListener, org.alfresco.util.transaction.TransactionListener, org.springframework.context.ApplicationListener

public class DefaultPropertyBackedBeanRegistry
extends Object
implements PropertyBackedBeanRegistry, org.springframework.context.ApplicationListener, TransactionListener

A default implementation of PropertyBackedBeanRegistry. An instance of this class will defer broadcasting PropertyBackedBeanEvents until it is notified that the database schema is available via a SchemaAvailableEvent. This allows listeners to potentially reconfigure the beans using persisted database information.

Registers a listener object that will be notified of register and deregister calls via a PropertyBackedBeanEvent.

Specified by:

addListener in interface PropertyBackedBeanRegistry

Parameters:

listener - the listener

register

public void register(PropertyBackedBean bean)

Description copied from interface: PropertyBackedBeanRegistry

Signals that a PropertyBackedBean has been initialized.

Specified by:

register in interface PropertyBackedBeanRegistry

Parameters:

bean - the bean

deregister

public void deregister(PropertyBackedBean bean,
 boolean isPermanent)

Description copied from interface: PropertyBackedBeanRegistry

Signals the PropertyBackedBeanUnregisteredEvent event.

Specified by:

deregister in interface PropertyBackedBeanRegistry

Parameters:

bean - the bean

isPermanent - is the component being destroyed forever, i.e. should persisted values be removed? On server shutdown, this value would be false, whereas on the removal of a dynamically created instance, this value would be true.

Parameters:

bean - the bean

broadcastRemoveProperties

public void broadcastRemoveProperties(PropertyBackedBean bean,
 Collection<String> properties)

Description copied from interface: PropertyBackedBeanRegistry

Signals that a PropertyBackedBean has been asked to remove properties.
