What kind of reasoner is produced by GenericRuleReasonerFactory?

Question

I have designed some rules and am wondering what the reasoner is is returned by the Jena's GenericRuleReasonerFactory (as shown in the following code)? Is it Racer, Pellet, or HermiT?

Reasoner reasoner = GenericRuleReasonerFactory.theInstance().create(configuration);

Answer 1

It's Jena's own rules engine.
