Interface INodeFactory

All Known Implementing Classes:

DefaultNodeFactory

public interface INodeFactory

Defines the methods for creation of INode instances.

This is the Abstract Factory of the Abstract Factory design pattern.

"Pluggable factories" allow the application to add its own custom implementations of the INode interface to the framework in a consitent, simple way. Custom implementations of the INode interface can thus be used as if they were a standard part of the framework.

Examples:

   MyCustomNodeFactory customFactory = new MyCustomNodeFactory();
   NodeFactory.setNodeFactory( customFactory );
 

Method Summary

INode	createNode() Creates a new empty INode instance.
INode	createNode(java.lang.Object aID) Creates a new INode instance with the specified identifier.
INode	createNode(java.lang.Object aID, java.lang.Object aValue) Creates a new INode instance with the specified identifier and value.
