Examples of com.hp.hpl.jena.rdf.model.Bag

com.hp.hpl.jena.rdf.model.Bag
An RDF Bag container.
This interface defines methods for accessing RDF Bag resources. These methods operate on the RDF statements contained in a model. The Bag implementation may cache state from the underlying model, so objects should not be added to or removed a the Bag by directly manipulating its properties, whilst the Bag is being accessed through this interface.

When a member is deleted from a Bag using this interface, or an iterator returned through this interface, all the other members with higher ordinals are renumbered using an implementation dependent algorithm.
