Examples of JenaGraph

org.apache.clerezza.rdf.jena.facade.JenaGraph
This class implements {@link com.hp.hpl.jena.graph.Graph} basingon a {@link org.apache.clerezza.rdf.core.TripleCollection}. A JenaGraph can be instanciated using mutable TripleCollections (i.e. MGraphS) as well as immutable ones (i.e. Graph), an attempt to add or remove triples to a JenaGraph based on an immutable TripleCollection will result in a UnsupportedOperationException being thrown by the underlying TripleCollection. Typically an instance of this class is passed as argument to {@link com.hp.hpl.jena.rdf.model.ModelFactory#createModelForGraph} toget a Model. @author reto
