Interface IMetaFactory

All Known Implementing Classes:

DefaultMetaFactory

public interface IMetaFactory

Defines the methods for creation of IMetaCollection instances.

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

If a client of the MetaFactory or graph package wishes to provide custom implementations of the IMetaCollection interface, they would also need to create a new IMetaFactory implementor. This IMetaFactory implementor would be set on the MetaFactory and would allow the new custom IMetaCollection instances to be used throughout the architecture.

Examples:

   MyCustomMetaFactory customFactory = new MyCustomMetaFactory();
   MetaFactory.setMetaFactory( customFactory );
 

Method Summary

IMetaCollection	createMetaCollection() Creates a new empty IMetaCollection instance.
IMetaCollection	createMetaCollection(INode aNode) Creates a new IMetaCollection that wraps the given INode instance.
IMetaCollection	createMetaCollection(java.lang.Object aID) Creates a new IMetaCollection instance with the specified identifier.
IMetaCollection	createMetaCollection(java.lang.Object aID, java.lang.Object aValue) Creates a new IMetaCollection instance with the specified identifier and value.
