Interface ResourceHome

All Known Implementing Classes:

ResourceHomeImpl, SingletonResourceHome

public interface ResourceHome

Defines a basic interface through which resources are discovered, and removed. The purpose of ResourceHome is to interact with a collection of resources of the same type. Each resource type will have its own custom implementation the ResourceHome interface. The implementation is expected to provide custom methods for creating new resources and optionally methods that act on a set of resource objects.

Method Summary

Resource	find(ResourceKey key) Retrives a resource.
Class	getKeyTypeClass() The resource key type.
QName	getKeyTypeName() The name of the resource key.
void	remove(ResourceKey key) Removes a resource.
