Example 1 with VARCHAR

use of com.facebook.presto.spi.type.StandardTypes.VARCHAR in project presto by prestodb.

the class TestPolymorphicScalarFunction method testSetsHiddenToTrueForOperators.

@Test
public void testSetsHiddenToTrueForOperators() {
    Signature signature = Signature.builder().operatorType(ADD).kind(SCALAR).returnType(parseTypeSignature("varchar(x)", ImmutableSet.of("x"))).argumentTypes(parseTypeSignature("varchar(x)", ImmutableSet.of("x"))).build();
    SqlScalarFunction function = SqlScalarFunction.builder(TestMethods.class).signature(signature).implementation(b -> b.methods("varcharToVarchar")).build();
    ScalarFunctionImplementation functionImplementation = function.specialize(BOUND_VARIABLES, 1, TYPE_REGISTRY, REGISTRY);
}

Example 2 with VARCHAR

use of com.facebook.presto.spi.type.StandardTypes.VARCHAR in project presto by prestodb.

the class TestPolymorphicScalarFunction method testTypeParameters.

@Test
public void testTypeParameters() throws Throwable {
    Signature signature = Signature.builder().name("foo").kind(SCALAR).typeVariableConstraints(comparableWithVariadicBound("V", VARCHAR)).returnType(parseTypeSignature("V")).argumentTypes(parseTypeSignature("V")).build();
    SqlScalarFunction function = SqlScalarFunction.builder(TestMethods.class).signature(signature).implementation(b -> b.methods("varcharToVarchar")).build();
    ScalarFunctionImplementation functionImplementation = function.specialize(BOUND_VARIABLES, 1, TYPE_REGISTRY, REGISTRY);
    Slice slice = (Slice) functionImplementation.getMethodHandle().invoke(INPUT_SLICE);
    assertEquals(slice, VARCHAR_TO_VARCHAR_RETURN_VALUE);
}
