broker collections package

This package contains utility classes that implement the ManageableCollection interface. Implementing this interface allows to use these classes as collection attributes in persistent classes.

The class ManageableVector extends Vector and implements ManageableCollections.

The class ManageableArrayList extends ArrayList and implements ManageableCollections.

The class ManageableHashSet extends HashSet and implements ManageableCollections.

Patterns applied: Adapter, Callback interface ("don't call us, we call you")

Todo: Provide more such implementations.
