Example 1 with VARCHAR_TO_VARCHAR_RETURN_VALUE

use of com.facebook.presto.metadata.TestPolymorphicScalarFunction.TestMethods.VARCHAR_TO_VARCHAR_RETURN_VALUE 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);
}
