Class GraknTitanGraph

java.lang.Object

ai.grakn.graph.internal.AbstractGraknGraph<com.thinkaurelius.titan.core.TitanGraph>

ai.grakn.graph.internal.GraknTitanGraph

All Implemented Interfaces:

GraknAdmin, GraknGraph, AutoCloseable

public class GraknTitanGraph
extends AbstractGraknGraph<com.thinkaurelius.titan.core.TitanGraph>

A Grakn Graph using TitanGraph as a vendor backend.

Wraps up a TitanGraph as a method of storing the Grakn Graph object Model. With this vendor some issues to be aware of: 1. Whenever a transaction is closed if none remain open then the connection to the graph is closed permanently. 2. Clearing the graph explicitly closes the connection as well.
