ai.grakn.factory

Class EmbeddedGraknSession

java.lang.Object

ai.grakn.factory.EmbeddedGraknSession

All Implemented Interfaces:

GraknSession, AutoCloseable

public class EmbeddedGraknSession
extends Object
implements GraknSession

Builds a TxFactory

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

commitLogHandler

public CommitLogHandler commitLogHandler()

create

public static EmbeddedGraknSession create(Keyspace keyspace,
                                          String engineUri)

This methods creates a EmbeddedGraknSession object for the remote API. A user should not call this method directly. See Grakn.session(String, String) for creating a GraknSession for the remote API

createEngineSession

public static EmbeddedGraknSession createEngineSession(Keyspace keyspace,
                                                       String engineUri,
                                                       GraknConfig config,
                                                       TxFactoryBuilder txFactoryBuilder)

Creates a EmbeddedGraknSession specific for internal use (within Engine), using provided Grakn configuration and disabling the remote (via REST) submission of commit log.
