Example 1 with PathsQuery

use of ai.grakn.graql.analytics.PathsQuery in project grakn by graknlabs.

the class GraqlTest method testPaths.

@Test
public void testPaths() throws InvalidKBException {
    addSchemaAndEntities();
    try (GraknTx graph = session.open(GraknTxType.WRITE)) {
        PathsQuery query = graph.graql().parse("compute paths from '" + entityId1 + "' to '" + entityId2 + "';");
        List<List<Concept>> path = query.execute();
        assertEquals(1, path.size());
        List<String> result = path.get(0).stream().map(Concept::getId).map(ConceptId::getValue).collect(Collectors.toList());
        List<String> expected = Lists.newArrayList(entityId1, relationId12, entityId2);
        assertEquals(expected, result);
    }
}

Example 2 with PathsQuery

use of ai.grakn.graql.analytics.PathsQuery in project grakn by graknlabs.
