Examples with OperatorTranslator org.apache.beam.sdk.extensions.euphoria.core.translate.OperatorTranslator used on opensource projects

Example 1 with OperatorTranslator

use of org.apache.beam.sdk.extensions.euphoria.core.translate.OperatorTranslator in project beam by apache.

the class GenericTranslatorProviderTest method testPredicateToTranslatorFunction.

@Test
public void testPredicateToTranslatorFunction() {
    AtomicBoolean predicateEvalValue = new AtomicBoolean(false);
    String translatorName = "translator";
    GenericTranslatorProvider provider = GenericTranslatorProvider.newBuilder().register(op -> predicateEvalValue.get(), AnyOpTranslator.ofName(translatorName)).build();
    Optional<OperatorTranslator<Void, Void, TestOperator>> maybeTranslator;
    maybeTranslator = provider.findTranslator(TestOperator.of());
    Assert.assertFalse(maybeTranslator.isPresent());
    Optional<OperatorTranslator<Void, Void, SecondTestOperator>> maybeSecondTranslator = provider.findTranslator(SecondTestOperator.of());
    Assert.assertFalse(maybeSecondTranslator.isPresent());
    predicateEvalValue.set(true);
    // now predicate will return true and we should get our translator
    maybeTranslator = provider.findTranslator(TestOperator.of());
    ProviderTestUtils.assertTranslator(translatorName, maybeTranslator, AnyOpTranslator.class);
    // we should get our translator for every operator's type
    maybeSecondTranslator = provider.findTranslator(SecondTestOperator.of());
    Assert.assertTrue(maybeSecondTranslator.isPresent());
}

Example 2 with OperatorTranslator

use of org.apache.beam.sdk.extensions.euphoria.core.translate.OperatorTranslator in project beam by apache.

the class GenericTranslatorProviderTest method testClassWithPredicateToTranslatorFunction.

@Test
public void testClassWithPredicateToTranslatorFunction() {
    AtomicBoolean predicateEvalValue = new AtomicBoolean(false);
    String translatorName = "translator";
    GenericTranslatorProvider provider = GenericTranslatorProvider.newBuilder().register(TestOperator.class, op -> predicateEvalValue.get(), TestOpTranslator.ofName(translatorName)).build();
    Optional<OperatorTranslator<Void, Void, TestOperator>> maybeTranslator;
    maybeTranslator = provider.findTranslator(TestOperator.of());
    Assert.assertFalse(maybeTranslator.isPresent());
    predicateEvalValue.set(true);
    // now predicate will return true and we should get our translator
    maybeTranslator = provider.findTranslator(TestOperator.of());
    ProviderTestUtils.assertTranslator(translatorName, maybeTranslator, TestOpTranslator.class);
    // we should not obtain operator for different operator class
    Optional<OperatorTranslator<Void, Void, SecondTestOperator>> maybeSecondTranslator = provider.findTranslator(SecondTestOperator.of());
    Assert.assertFalse(maybeSecondTranslator.isPresent());
