ai.grakn.factory

Class GraknSessionImpl

java.lang.Object

ai.grakn.factory.GraknSessionImpl

All Implemented Interfaces:

GraknSession, AutoCloseable

public class GraknSessionImpl
extends Object
implements GraknSession

Builds a TxFactory

This class facilitates the construction of GraknTx by determining which factory should be built. It does this by either defaulting to an in memory tx GraknTxTinker or by retrieving the factory definition from engine. The deployment of engine decides on the backend and this class will handle producing the correct graphs.
