Added a method to know whether a given method is part of a CtType

[arnobl]

Hey all,
As suggested on the mailing list, here is a PR to add a method in CtType to know whether a given type has a method (inherited or not, abstract or implemented). Look at the Javadoc for more details. Let me know if you want me to change the behaviour of the added method (replacing PR 870).

This method is quite handy to know whether one can call a method on typed variable.

I wonder if using a signature-based test would be better than an object-based test.

Ie replacing method.getParent() == this by

final String sig = method.getSignature();
for(CtMethod<?> m : getMethods()) {
    if(m.getSignature().equals(sig)) {
        return true;
    }
}

Obviously, this behavior supersedes the current one.

What do you think?

[arnobl]

Yes, the object-based test is not mandatory but just an optimisation. I can remove it. Tell me.

[monperrus]

let's go for a signature-based test then

[monperrus]

The matching criterion is that the signatures are identical.

thanks a lot for this contribution
