// We enforce following behaviour:
// 1. Try our own extractor to check for annotations on setter method.
// 2. Try to fetch info via reflection (e.g. by methods or property)
// 3. Use php doc as fallback
// We do this because of:
// Most of the time we can just use the TypeHint of setter or add/remove for collections
// Sometimes we have to deal with multiple types (e.g. string and array)
// We then can have a different property name and no type hint, reflection will fail
// But we can use PHPDoc to define all supported
// And we can overrule the symfony behaviour first of all with our own extractor taking precedence.
//
// The reflection will first check mutator, then getter followed from properties.
// The phpdoc will first check the property itself.
