Interface URIProvider

@ProviderType
public interface URIProvider

Provides a URI in exchange for a Resource. Typically the Resource will represent something where is a URI is valiable and usefull. Implementations of this interface must ensure that the any underlying security model is delegated securely and not circumvented. Typically resource provider bundles should implement this provider as in most cases internal implementation details of the resource will be required to achieve the implementation. Ideally implementations should be carefully reviewed by peers.
