[forge-dev] How to get value as class from annotation?

[George Gastaldi]

Hy Doychin,

We provide a "getClassValue()" in this case, so your code should be like:

                        AnnotationSource<JavaClassSource> idClassAnotation
= entityClass
                                        .getAnnotation(IdClass.class);
                        Class<?> valueClass =
idClassAnotation.getClassValue();

Note that this method may fail if the ClassLoader fails to load the class
(if the ID Class is part of the project, for example). In this case, you
can load the class by using the ClassLoaderFacet from the project:

try (URLClassLoader cl =
project.getFacet(ClassLoaderFacet.class).getClassLoader()) {
     // call cl.loadClass(yourClassName);
}

Hope that helps,

Best Regards!
