Creating a method with generic type parameters

[William Burke]

With Gizmo, is it possible to generate a method that has generic type signatures?  Example somewhere?  Searching...

Thanks,

Bill

It is, you need to set signature manually (gizmo has method for that)

I'm on a phone now, but I do remember spring data and resteasy reactive extensions doing that.

I see examples of creating MethodDescriptor based on strings pulled from Jandex classes (Type, MethodInfo, ClassInfo, etc...), but I don't have access to a Jandex object, only reflection, and can't grok the syntax so far.

The method here should give you all the information you need:

https://github.com/quarkusio/quarkus/blob/main/extensions/panache/rest-data-panache/deployment/src/main/java/io/quarkus/rest/data/panache/deployment/utils/SignatureMethodCreator.java#L35-L70

Calling MethodCreator#setSignature() is the way to go and the syntax is described in the Javadoc.
