Class SampleKBLoader

java.lang.Object

ai.grakn.util.SampleKBLoader

public class SampleKBLoader
extends Object

Builds GraknTx bypassing engine.

A helper class which is used to build GraknTx for testing purposes. This class bypasses requiring an instance of engine to be running in the background. Rather it acquires the necessary properties for building a graph directly from system properties. This does however mean that commit logs are not submitted and no post processing is ran
