Determine the load state of a given persistent attribute.

Specified by:

entity - entity containing the attribute

isLoaded

public boolean isLoaded(java.lang.Object entity)

Description copied from interface: PersistenceUtil

Determine the load state of an entity. 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.

Specified by:

isLoaded in interface PersistenceUtil

Parameters:

entity - whose load state is to be determined

Returns:

false if the entity has not been loaded, else true
