Method Detail

setRootId

void setRootId(PersistentIdentifier id)

getRoot

PersistentContextServices.ObjectReference getRoot()
                                                  throws PersistenceException

Throws:

PersistenceException

get

PersistentContextServices.ObjectReference get(PersistentIdentifier id)

Return the object reference associated to the id indicated as parameter. Can't create a new object reference for the passed object if it not exists. If not has object reference associated to the id passed return null.

Parameters:

id -

Returns:

the object reference or null.

get

PersistentContextServices.ObjectReference get(Object obj)

Return the object reference associated to the object passed as parameter. Can't create a new object reference for the passed object if it not exists. If not has object reference associated to the id passed return null.

Parameters:

obj -

Returns:

the object reference or null.

get

PersistentContextServices.ObjectReference get(PersistentState state)
                                              throws PersistenceException

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.

Parameters:

state -

Returns:

Throws:

PersistenceException

update

void update(PersistentContextServices.ObjectReference ref)
            throws PersistenceException

Update the object referenced by ref, recreating it with this state,

Parameters:

ref -

Throws:

PersistenceException

add

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

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.

Parameters:

state -

obj -

Returns:

the object reference.

Throws:

PersistenceException

add

PersistentContextServices.ObjectReference add(PersistentIdentifier id)
                                              throws PersistenceException

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

Parameters:

id -

Returns:

Throws:

PersistenceException

clear

void clear()

PersistenceException

getId

PersistentIdentifier getId(Object obj)
                           throws PersistenceException
