Example 8 with StmtIterator

use of org.apache.jena.rdf.model.StmtIterator in project jena by apache.

the class TestReasoners method testTransitiveSpecReuse.

/**
     * The reasoner contract for bind(data) is not quite precise. It allows for
     * reasoners which have state so that reusing the same reasoner on a second data
     * model might lead to interference. This in fact used to happen with the transitive
     * reasoner. This is a test to check the top level symptoms of this which can be
     * solved just be not reusing reasoners.
     * @todo this test might be better moved to OntModel tests somewhere
