ai.grakn.factory

Class TxFactoryAbstract<Tx extends EmbeddedGraknTx<G>,G extends org.apache.tinkerpop.gremlin.structure.Graph>

java.lang.Object

ai.grakn.factory.TxFactoryAbstract<Tx,G>

Type Parameters:

Tx - A GraknTx extending EmbeddedGraknTx and wrapping a Tinkerpop Graph

G - A vendor implementation of a Tinkerpop Graph

All Implemented Interfaces:

TxFactory<G>

Direct Known Subclasses:

TxFactoryTinker

public abstract class TxFactoryAbstract<Tx extends EmbeddedGraknTx<G>,G extends org.apache.tinkerpop.gremlin.structure.Graph>
extends Object
implements TxFactory<G>

Defines the abstract construction of GraknTxs on top of Tinkerpop Graphs. For this factory to function a vendor specific implementation of a graph extending EmbeddedGraknTx must be provided. This must be provided with a matching TinkerPop Graph which is wrapped within the GraknTx
