Interface ListMutator
- All Superinterfaces:
- PropertyMutator
- All Known Implementing Classes:
- AbstractListMutator, DefaultListMutator
- public interface ListMutator
- extends PropertyMutator
Extends PropertyMutator to provide access to the members of a multi-valued property value. This allows the mutator to properly manage list change notifications even if the actual storage object does not. For example, standard java.util.List based properties can't be expected to manage the complexities of element change notification, insertions, etc.. The mutator wraps this support around the real value.
