Converts persistence-capable instance to EJBLocalObject.

Specified by:

convertPCToEJBLocalObject in interface JDOEJB20Helper

Parameters:

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

pm - the associated instance of PersistenceManager.

Returns:

instance of EJBLocalObject.

convertPCToEJBLocalObject

public 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.

Specified by:

convertPCToEJBLocalObject in interface JDOEJB20Helper

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

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

Specified by:

convertEJBLocalObjectToPC in interface JDOEJB20Helper

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

public Collection convertCollectionPCToEJBLocalObject(Collection pcs,
