Parameters:

model - The data to update. If the type URI is null it is not updated. If role 1 is null it is not updated. If role 2 is null it is not updated.

delete

public void delete()

Description copied from class: AttachedDeepaMehtaObject

Deletes all sub-topics of this DeepaMehta object (associated via "dm4.core.composition", recursively) and deletes all the remaining direct associations of this DeepaMehta object.

Note: deletion of the object itself is up to the subclasses.

Specified by:

delete in interface DeepaMehtaObject

Overrides:
