public class OWLRDFConsumer
extends Object
implements RDFConsumer, org.semanticweb.owlapi.util.AnonymousNodeChecker

A parser/interpreter for an RDF graph which represents an OWL ontology. The consumer interprets triple patterns in the graph to produce the appropriate OWLAPI entities, class expressions and axioms. The parser is based on triple handlers. A given triple handler handles a specific type of triple. Generally speaking this is based on the predicate of a triple, for example, A rdfs:subClassOf B is handled by a subClassOf handler. A handler determines if it can handle a triple in a streaming mode (i.e. while parsing is taking place) or if it can handle a triple after parsing has taken place and the complete graph is in memory. Once a handler handles a triple, that triple is deemed to have been consumed an is discarded. The parser attempts to consume as many triples as possible while streaming parsing is taking place. Whether or not a triple can be consumed during parsing is determined by installed triple handlers.
