Examples with Predicate com.yahoo.document.predicate.Predicate used on opensource projects

Example 1 with Predicate

use of com.yahoo.document.predicate.Predicate in project vespa by vespa-engine.

the class OptimizePredicateTestCase method requireThatOptimizerIsCalledWithCloneOfInput.

@Test
public void requireThatOptimizerIsCalledWithCloneOfInput() {
    final Predicate predicateA = Mockito.mock(Predicate.class);
    final Predicate predicateB = Mockito.mock(Predicate.class);
    final PredicateFieldValue input = new PredicateFieldValue(predicateA);
    ExecutionContext ctx = new ExecutionContext().setValue(input).setVariable("arity", new IntegerFieldValue(10));
    FieldValue output = new OptimizePredicateExpression((predicate, options) -> {
        assertNotSame(predicateA, predicate);
        return predicateB;
    }).execute(ctx);
    assertNotSame(output, input);
    assertTrue(output instanceof PredicateFieldValue);
    assertSame(predicateB, ((PredicateFieldValue) output).getPredicate());
}

Example 2 with Predicate

use of com.yahoo.document.predicate.Predicate in project vespa by vespa-engine.

the class FeatureConjunctionTransformer method convertConjunction.

/**
 * Conversion rules:
 *  1) A {@link FeatureConjunction} may only consist of FeatureSets having unique keys.
 *     If multiple {@link FeatureSet} share the same key, they have to be placed into separate FeatureConjunctions.
 *  2) A FeatureConjunction must have at least 2 operands.
 *  3) Any operand that is not a FeatureSet, negated or not,
 *     (e.g {@link FeatureRange}) cannot be placed into a FeatureConjunction.
 *  4) All FeatureSets may only have a single value.
 *
 *  See the tests in FeatureConjunctionTransformerTest for conversion examples.
