Implements javax.persistence.PersistenceUnitUtil.getIdentifier.

Doc from javax.persistence.PersistenceUnitUtil.getIdentifier.

public boolean isLoaded(Object entity, String attributeName)

Implements javax.persistence.PersistenceUnitUtil.isLoaded.

Doc from javax.persistence.PersistenceUnitUtil.isLoaded.

Determine the load state of a given persistent attribute of an entity belonging to the persistence unit.

Parameters
entity:Object

entity instance containing the attribute

attributeName:String

name of attribute whose load state is to be determined

Returns:boolean

false if entity's state has not been loaded or if the attribute state has not been loaded, else true

public boolean isLoaded(Object entity)

Implements javax.persistence.PersistenceUnitUtil.isLoaded.

Doc from javax.persistence.PersistenceUnitUtil.isLoaded.

Determine the load state of an entity belonging to the persistence unit. This method can be used to determine the load state of an entity passed as a reference. An entity is considered loaded if all attributes for which FetchType.EAGER has been specified have been loaded.

The isLoaded(Object, String) method should be used to determine the load state of an attribute. Not doing so might lead to unintended loading of state.

Parameters
entity:Object

entity instance whose load state is to be determined

Returns:boolean

false if the entity has not been loaded, else true
