          org.progeeks.meta.AbstractListMutator
              org.progeeks.meta.DefaultListMutator

All Implemented Interfaces:

java.lang.Iterable, java.util.Collection, java.util.List, ListMutator, PropertyMutator, ObservableList

Direct Known Subclasses:

AbstractMetaObject.BaseListMutator

public abstract class DefaultListMutator
extends AbstractListMutator
implements ListMutator

A default implementation of ListMutator that will work with any MetaObject, given certain restrictions. It can be used as an implementation on its own or subclassed to provide performance improvements in metakit implementation specific cases. Subclasses must implement the firePropertyChangeEvent() event method to support delivery of list change events.
