public class CSubsMulti
extends ContextSubscriber

Class used to register multiple subscribers, each of them using just a single mcontext event pattern, and having an associated SPARQL CONSTRUCT query. Each patter is given by a restriction for the subject, the predicate and the object for a mcontext-event at the bus, where the last two are optional. See also the class Situation in the ontology for the reasoner.
