Examples of com.hp.hpl.jena.shared.PrefixMapping

com.hp.hpl.jena.shared.PrefixMapping
Methods for recording namepsace prefix mappings and applying and unapplying them to URIs.
Note that a Model *is* a PrefixMapping, so all the PrefixMapping operations apply to Models, and a Model can be used to supply the PrefixMapping argument to setNsPrefixes.
