Examples with TypeImplementationDependency io.trino.operator.annotations.TypeImplementationDependency used on opensource projects

Example 1 with TypeImplementationDependency

use of io.trino.operator.annotations.TypeImplementationDependency in project trino by trinodb.

the class TestAnnotationEngineForScalars method testConstructorInjectionScalarParse.

@Test
public void testConstructorInjectionScalarParse() {
    Signature expectedSignature = new Signature("parametric_scalar_inject_constructor", ImmutableList.of(typeVariable("T")), ImmutableList.of(), BIGINT.getTypeSignature(), ImmutableList.of(arrayType(new TypeSignature("T"))), false);
    List<SqlScalarFunction> functions = ScalarFromAnnotationsParser.parseFunctionDefinition(ConstructorInjectionScalarFunction.class);
    assertEquals(functions.size(), 1);
    ParametricScalar scalar = (ParametricScalar) functions.get(0);
    assertImplementationCount(scalar, 2, 0, 1);
    List<ParametricScalarImplementationChoice> parametricScalarImplementationChoices = scalar.getImplementations().getGenericImplementations().get(0).getChoices();
    assertEquals(parametricScalarImplementationChoices.size(), 1);
    List<ImplementationDependency> dependencies = parametricScalarImplementationChoices.get(0).getDependencies();
    assertEquals(dependencies.size(), 0);
    List<ImplementationDependency> constructorDependencies = parametricScalarImplementationChoices.get(0).getConstructorDependencies();
    assertEquals(constructorDependencies.size(), 1);
    assertTrue(constructorDependencies.get(0) instanceof TypeImplementationDependency);
    FunctionMetadata functionMetadata = scalar.getFunctionMetadata();
    assertEquals(functionMetadata.getSignature(), expectedSignature);
    assertTrue(functionMetadata.isDeterministic());
    assertFalse(functionMetadata.isHidden());
    assertEquals(functionMetadata.getDescription(), "Parametric scalar with type injected though constructor");
}

Example 2 with TypeImplementationDependency

use of io.trino.operator.annotations.TypeImplementationDependency in project trino by trinodb.

the class TestAnnotationEngineForAggregates method testInjectTypeAggregateParse.

@Test

    Signature expectedSignature = new Signature("inject_type_aggregate", ImmutableList.of(typeVariable("T")), ImmutableList.of(), new TypeSignature("T"), ImmutableList.of(new TypeSignature("T")), false);
    ParametricAggregation aggregation = getOnlyElement(parseFunctionDefinitions(InjectTypeAggregateFunction.class));
    assertEquals(aggregation.getFunctionMetadata().getDescription(), "Simple aggregate with type injected");
    assertTrue(aggregation.getFunctionMetadata().isDeterministic());
    assertEquals(aggregation.getFunctionMetadata().getSignature(), expectedSignature);
    ParametricImplementationsGroup<AggregationImplementation> implementations = aggregation.getImplementations();
    assertEquals(implementations.getGenericImplementations().size(), 1);
    AggregationImplementation implementation = implementations.getGenericImplementations().get(0);

    assertTrue(implementation.getCombineDependencies().get(0) instanceof TypeImplementationDependency);
    assertTrue(implementation.getOutputDependencies().get(0) instanceof TypeImplementationDependency);
    assertFalse(implementation.hasSpecializedTypeParameters());
    assertEquals(implementation.getInputParameterKinds(), ImmutableList.of(STATE, INPUT_CHANNEL));
    BoundSignature boundSignature = new BoundSignature(aggregation.getFunctionMetadata().getSignature().getName(), DoubleType.DOUBLE, ImmutableList.of(DoubleType.DOUBLE));
