                                   throws PersistenceException

Description copied from interface: PersistentContextServices

Create a new identifier based on the string passed as parameter and return this. Throws a exception if the identifier passed as parameter has conflict with another identifier.

Specified by:

getIdentifier in interface PersistentContextServices

Returns:

Throws:

PersistenceException

add

public PersistentContextServices.ObjectReference add(PersistentIdentifier id)
                                              throws PersistenceException

Description copied from interface: PersistentContextServices

Add a new reference associated to the identifier passed as parameter. If already exists an object reference for this id, return this.

Specified by:

add in interface PersistentContextServices

Returns:

Throws:

PersistenceException

add

public PersistentContextServices.ObjectReference add(PersistentState state,
                                            Object obj)
                                              throws PersistenceException

Description copied from interface: PersistentContextServices

Add a reference to the object associated to the state. If reference already exits and obj not is null, it is updated with obj. If obj is null, the add the object reference with the state and the object to null. Return the created or updated object reference.

Specified by:

add in interface PersistentContextServices

Returns:

the object reference.

Throws:

PersistenceException

get

public PersistentContextServices.ObjectReference get(PersistentState state)
                                              throws PersistenceException

Description copied from interface: PersistentContextServices

Return the object reference associated to the state passed as parameter. If not exists an object reference associated to the state, then a new object reference is created, registered and returned. Don't modify or update the object in the reference, it can be null.

Specified by:

get in interface PersistentContextServices

Returns:

Throws:

PersistenceException

get

Specified by:

get in interface PersistentContextServices

Returns:

the object reference or null.

get

public PersistentContextServices.ObjectReference get(Object obj)

Description copied from interface: PersistentContextServices

Specified by:

get in interface PersistentContextServices

Returns:

the object reference or null.

update

public void update(PersistentContextServices.ObjectReference ref)
            throws PersistenceException
