Class EngineGraknTxFactory

java.lang.Object

ai.grakn.engine.factory.EngineGraknTxFactory

public class EngineGraknTxFactory
extends Object

Engine's internal GraknTx Factory

This internal factory is used to produce GraknTxs. It is also worth noting that both this class and Grakn.session(String, String) us the same FactoryBuilder. This means that graphs produced from either factory pointing to the same keyspace are actually the same graphs.
