Method Detail

convertPCToEJBLocalObject

jakarta.ejb.EJBLocalObject convertPCToEJBLocalObject(Object pc,
                                                     PersistenceManager pm)

Converts persistence-capable instance to EJBLocalObject.

Parameters:

pc - the persistence-capable instance to be converted as an Object.

pm - the associated instance of PersistenceManager.

Returns:

instance of EJBLocalObject.

convertPCToEJBLocalObject

jakarta.ejb.EJBLocalObject convertPCToEJBLocalObject(Object pc,
                                                     PersistenceManager pm,
                                                     jakarta.ejb.EJBContext context)

Converts persistence-capable instance to EJBLocalObject. Returns null if the instance is already removed via cascade-delete operation.

Parameters:

pc - the persistence-capable instance to be converted as an Object.

pm - the associated instance of PersistenceManager.

context - the EJBContext of the calling bean.

Returns:

instance of EJBLocalObject.

convertEJBLocalObjectToPC

Object convertEJBLocalObjectToPC(jakarta.ejb.EJBLocalObject o,
                                 PersistenceManager pm,
                                 boolean validate)

Converts EJBLocalObject to persistence-capable instance.

Parameters:

o - the EJBLocalObject instance to be converted.

pm - the associated instance of PersistenceManager.

validate - true if the existence of the instance is to be validated.

Returns:

persistence-capable instance.

Throws:

IllegalArgumentException - if validate is true and instance does not exist in the database or is deleted.

convertCollectionPCToEJBLocalObject

Collection convertCollectionPCToEJBLocalObject(Collection pcs,
                                               PersistenceManager pm)

Converts Collection of persistence-capable instances to a Collection of EJBLocalObjects.

Parameters:

pcs - the Collection of persistence-capable instance to be converted.

pm - the associated instance of PersistenceManager.

Returns:

Collection of EJBLocalObjects.

convertCollectionPCToEJBLocalObjectSet

Set convertCollectionPCToEJBLocalObjectSet(Collection pcs,
                                           PersistenceManager pm)

Converts Collection of persistence-capable instances to a Set of EJBLocalObjects.

Parameters:

pcs - the Collection of persistence-capable instance to be converted.

pm - the associated instance of PersistenceManager.

Returns:

Set of EJBLocalObjects.

convertCollectionEJBLocalObjectToPC

Collection convertCollectionEJBLocalObjectToPC(Collection coll,

                                               boolean validate)

Converts Collection of EJBLocalObjects to a Collection of persistence-capable instances.

Parameters:

coll - the Collection of EJBLocalObject instances to be converted.

pm - the associated instance of PersistenceManager.

validate - true if the existence of the instances is to be validated.

Returns:

Collection of persistence-capable instance.

Throws:

IllegalArgumentException - if validate is true and at least one instance does not exist in the database or is deleted.

assertInstanceOfLocalInterfaceImpl

void assertInstanceOfLocalInterfaceImpl(Object o)

Validates that this instance is of the correct implementation class of a local interface type.

Parameters:

o - the instance to validate.

Throws:

IllegalArgumentException - if validation fails.
