Class GraknTinkerGraph

java.lang.Object

ai.grakn.graph.internal.AbstractGraknGraph<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>

ai.grakn.graph.internal.GraknTinkerGraph

All Implemented Interfaces:

GraknGraph, GraknAdmin, AutoCloseable

public class GraknTinkerGraph
extends AbstractGraknGraph<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>

A Grakn Graph using TinkerGraph as a vendor backend.

Wraps up a TinkerGraph as a method of storing the Grakn Graph object Model. With this vendor some exceptions are in place: 1. Transactions do not exists and all threads work on the same graph at the same time. 2. The rollback() operation is unsupported due to Tinkerpop Transactions not being supported.

Method Detail

isConceptModified

public boolean isConceptModified(ai.grakn.graph.internal.ConceptImpl concept)

Specified by:

isConceptModified in class AbstractGraknGraph<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>

Parameters:

concept - A concept in the graph

Returns:

true all the time. There is no way to know if a TinkerVertex has been modified or not.

getConceptByBaseIdentifier

public <T extends Concept> T getConceptByBaseIdentifier(Object baseIdentifier)

Overrides:

getConceptByBaseIdentifier in class AbstractGraknGraph<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>

rollback

public void rollback()

Description copied from interface: GraknGraph

Resets the current transaction without committing.

Specified by:

rollback in interface GraknGraph

Overrides:

rollback in class AbstractGraknGraph<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>
