How to get parameter type in reflected class method?

I'm trying to get type $bar variable.

<?php
class Foo
{
    public function test(stdClass $bar)
    {

    }
}

$reflect = new ReflectionClass('Foo');
foreach ($reflect->getMethods() as $method) {
    foreach ($method->getParameters() as $num => $parameter) {
        var_dump($parameter->getType());
    }
}

I expect stdClass but I get

Call to undefined method ReflectionParameter::getType()

What can be wrong? Or there is some another way?..
