Class GraqlTraversal

java.lang.Object

ai.grakn.graql.internal.gremlin.GraqlTraversal

public class GraqlTraversal
extends Object

A traversal over a Grakn graph, representing one of many ways to execute a MatchQuery. Comprised of ordered Fragments which are used to construct a TinkerPop GraphTraversal, which can be retrieved and executed.
