While working with the reflection class and annotations I have found that there is no clear way to reference a method name in a compile-time safe way. What I really want is to be able to reference a method within an annotation. Might look something like:
@CallAfter(method=Foo.class.foo())
void Bar() { ... }
At the moment you can only do this with strings, which is not compile time safe.. This is a problem because it undermines Java being statically typed. The only solution I have found is something like what is below. However this still does not help with referencing a method in an annotation. :(
public static String methodName = null;
public static void main(String[] args) {
// .foo() is compile-time safe
loadMethodName(IFoo.class).foo();
System.out.println(methodName);
}
public static <T> T loadMethodName(Class<T> mock) {
return (T) Proxy.newProxyInstance(mock.getClassLoader(), new Class[] { mock },
(obj, method, args) -> {
methodName = method.getName();
return null;
});
}
public interface IFoo {
Object foo();
}
Does only one have any thoughts, comments, or a solution to this?
What I think would be the most elegant solution would be if Java auto built Enums for class names, fields, and methods. Then everyone could metaprogram in a compile-time safe way =)
