Class Registry

java.lang.Object
  de.grogra.pf.registry.Registry

All Implemented Interfaces:

GraphTransaction.Consumer, SharedObjectProvider, SharedObjectProvider.Binding, Transaction.Consumer, XAListener, RegistryContext, TypeLoader, TreeDiff.NodeModel, javax.swing.tree.TreeModel

public final class Registry
extends java.lang.Object
implements Transaction.Consumer, GraphTransaction.Consumer, XAListener, SharedObjectProvider, SharedObjectProvider.Binding, javax.swing.tree.TreeModel, RegistryContext, TreeDiff.NodeModel, TypeLoader

The registry consists of a tree of items. Each item has a name and can be referenced like in a file system. The path for selecting an item is similar to a unix path (i. e. /ui/commands).
