How to read custom class annotation in extension

[MartinMystikJonas]

In custom return type extension i need to read custom annotation from class but I was not able to figure out how to do it.

I get called type like this: $calledOnType = $scope->getType($methodCall->var);

which references class or interface which should have @entityType someClass annotation.

So I need to get value ("someClass") from this annotation and resolve it to FQN of class so I can create ObjectType.

Any help would be appreciated. Thanks.

I'd do something like this:

$classNames = TypeUtils::getDirectClassNames($calledOnType);
foreach ($classNames as $className) {
    if (!$this->reflectionProvider->hasClass($className)) { // inject "PHPStan\Reflection\ReflectionProvider" in the constructor
        continue;
    }

    $classReflection = $this->reflectionProvider->getClass($className);
    $phpDoc = $classReflection->getResolvedPhpDoc();
    if ($phpDoc === null) {
        continue;
    }
    // there's `$phpDoc->getPhpDocNodes()`, an array of PHPStan\PhpDocParser\Ast\PhpDoc\PhpDocNode objects
    // it's an array because of complexities related to implicit phpDoc inheritance from parent methods etc.
    // you should be able to get your tag on PhpDocNode easily, it's gonna be PHPStan\PhpDocParser\Ast\PhpDoc\GenericTagValueNode most likely
}

This needs dev-master because of these changes:

• phpstan/phpstan-src@04a23d3
• phpstan/phpstan-src@e70e00d

I managet to get it to work except last issue. I was not able to figure aut how to translate class name to FQN if Annotation used just short class name. I originally thought $scope->getType would do it (but int needs Expr and I have only string) or that I can use TypeStringResolver but I do not know how to correctly get/ceate NameScope to pass as 2nd argument.
