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.

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.

numOpenTx

public int numOpenTx()

Specified by:

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

Returns:

The number of open transactions currently.

isConnectionClosed

public boolean isConnectionClosed()

Specified by:

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

commit

public void commit()

Description copied from interface: GraknGraph

Commits any changes to the graph and closes the transaction. You must use the GraknSession to get a new open transaction.

Specified by:

commit in interface GraknGraph

Overrides:

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

abort

public void abort()

Description copied from interface: GraknGraph

Reverts any changes done to the graph and closes the transaction. You must use the GraknSession to get a new open transaction.

Specified by:

abort in interface GraknGraph

Overrides:

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

getConceptRawId

public <T extends Concept> T getConceptRawId(Object id)

Description copied from class: AbstractGraknGraph

Looks up concept by using id against vertex ids. Does not use the index. This is primarily used to fix duplicates when indicies cannot be relied on.

Overrides:

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

Parameters:

id - The id of the concept which should match the vertex id

Returns:

The concept if it exists.
