Class ComponentStoreImpl

java.lang.Object

net.sf.jguiraffe.gui.forms.ComponentStoreImpl

All Implemented Interfaces:

ComponentStore

public class ComponentStoreImpl
extends Object
implements ComponentStore

A fully functional default implementation of the ComponentStore interface.

This implementation keeps the managed components and handlers in maps where they can directly be accessed. The components of the stored component handlers are also put in the map for the components, so the name spaces of these entities are not disjunct.

For field handlers situation is similar: The component handlers associated to the added field handlers will be added to the map with the component handlers, too (and their components will in turn be added to the component map). So access to the stored entities is somewhat hierarchical.
