Examples of RDFHandler

org.openrdf.rio.RDFHandler
An interface defining methods related to RDF data handling. RDFHandler is both used as a "consumer" and as a "producer" interface. As such it can be used both as an interface for receiving RDF data, for example by listening to the results of an RDF parser, and as an interface for reporting RDF data, for example to an object that serializes RDF data to an RDF/XML document.
