Cannot extend ReflectionMethod

[sirsnyder]

Hello Joe,

\Thread::extend(\ReflectionClass::class);

works like a charm! However

\Thread::extend(\ReflectionMethod::class);

throws an RuntimeException "cannot extend class ReflectionMethod, it already extends ReflectionFunctionAbstract". So I tried to extend ReflectionFunctionAbstract, but ReflectionFunctionAbstract is a trait and can't be extended.

\Thread::extend(\ReflectionFunctionAbstract::class);

cannot extend trait ReflectionFunctionAbstract

Shouldn't it be possible to extend ReflectionMethod, cause ReflectionFunctionAbstract is just a trait and no parent class of ReflectionMethod?

Thanks and keep up the good work!

I've checked ReflectionClass::isTrait(), it's false

var_dump((new \ReflectionClass(\ReflectionFunctionAbstract::class))->isTrait());

Thanks for report ...

On a side note, this is not likely to do what you think it will.

There is no automatic way to tell at runtime if an internal class will behave itself after it has been extended.

It is likely that a class with a create_object handler set will not work, but it's not always the case.

Threaded::extend is intended for user land classes really, but you are free to mess about with internal classes.

Thx for the explanation, I will keep that in mind. Problem is, a ReflectionClass instance as class member must not be serialized/unseralized, otherwise it's broken.

Extending ReflectionClass seems to help in this particular case(will observe the behavior of the Reflection* classes).
