    typeDecider
    The type decider can decide for a given RDFNode whether a certain class can act as a view for it for a given view write out those triples to an RDFNode such that the type decider will consider the original view as applicable If you get an exception on typeDecider such as java.lang.NullPointerException ensure to call JenaSystem.init() before calling methods on this class
