public interface DynamicModel

extends com.hp.hpl.mesa.rdf.jena.model.Model

An RDF Model that provides a mechanism to dynamically load referenced namespaces on an as needed basis. When the properties of a Resource are accessed the model checks to see if the namespace of the resource has been loaded into the model. If not, the namespace is loaded before the accessor method returns. This model makes the assumption that the namespace of a resource is the URL of the file that defines the resource. Please be careful when using StmtIterators on a DynamicModel because a dynamic load modifes the model supporting the iterator which causes an error.

Method Summary

boolean	dynamicLoad() Returns true if dynamic loading is enabled.
java.util.Set	getLoadedURLs() List which URLs have been loaded.
boolean	isLoaded(java.lang.String url) Returns true if the given URL has been loaded into the model.
boolean	setDynamicLoad(boolean dynamicp) Enable or disable dynamic loading.
