Container for all ORM events.

This class cannot be instantiated.

Constants

preRemove

The preRemove event occurs for a given entity before the respective EntityManager remove operation for that entity is executed.

This is an entity lifecycle event.

postRemove

The postRemove event occurs for an entity after the entity has been deleted. It will be invoked after the database delete operations.

This is an entity lifecycle event.

prePersist

The prePersist event occurs for a given entity before the respective EntityManager persist operation for that entity is executed.

This is an entity lifecycle event.

postPersist

The postPersist event occurs for an entity after the entity has been made persistent. It will be invoked after the database insert operations.

Generated primary key values are available in the postPersist event.

This is an entity lifecycle event.

preUpdate

The preUpdate event occurs before the database update operations to entity data.

This is an entity lifecycle event.

postUpdate

The postUpdate event occurs after the database update operations to entity data.

This is an entity lifecycle event.

postLoad

The postLoad event occurs for an entity after the entity has been loaded into the current EntityManager from the database or after the refresh operation has been applied to it.

Note that the postLoad event occurs for an entity before any associations have been initialized. Therefore it is not safe to access associations in a postLoad callback or event handler.

This is an entity lifecycle event.

loadClassMetadata

The loadClassMetadata event occurs after the mapping metadata for a class has been loaded from a mapping source (annotations/xml).

onClassMetadataNotFound

The onClassMetadataNotFound event occurs whenever loading metadata for a class failed.

preFlush

The preFlush event occurs when the EntityManager#flush() operation is invoked, but before any changes to managed entities have been calculated. This event is always raised right after EntityManager#flush() call.

onFlush

The onFlush event occurs when the EntityManager#flush() operation is invoked, after any changes to managed entities have been determined but before any actual database operations are executed. The event is only raised if there is actually something to do for the underlying UnitOfWork. If nothing needs to be done, the onFlush event is not raised.

postFlush

The postFlush event occurs when the EntityManager#flush() operation is invoked and after all actual database operations are executed successfully. The event is only raised if there is actually something to do for the underlying UnitOfWork. If nothing needs to be done, the postFlush event is not raised. The event won't be raised if an error occurs during the flush operation.

onClear

The onClear event occurs when the EntityManager#clear() operation is invoked, after all references to entities have been removed from the unit of work.
