}

Example 57 with QueryBuilder

use of ai.grakn.graql.QueryBuilder in project grakn by graknlabs.

the class ReasoningTests method reusingResources_definingResourceThroughOtherResourceWithConditionalValue.

// Expected result: When the head of a rule contains resource assertions, the respective unique resources should be generated or reused.
@Test

    assertEquals(answers.size(), 1);
}

Example 58 with QueryBuilder

use of ai.grakn.graql.QueryBuilder in project grakn by graknlabs.
