Class GraknSessionImpl

java.lang.Object

ai.grakn.factory.GraknSessionImpl

All Implemented Interfaces:

GraknSession, AutoCloseable

public class GraknSessionImpl
extends Object
implements GraknSession

Builds a Grakn Graph factory

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