Eclipse JDT Refactor method programatically fails in subclass

Question

I am using org.eclipse.jdt.core.IMethod and calling method.rename(newName, true, new NullProgressMonitor()); on an interface.

It refactors interface method, but fails to refactor its implementation classes-methods.

For example:

interface Animal {
    void eat(); // refactors here
}

class Dog implements Animal {

    // fails to refactor this
    void eat() {
    }
}

Kindly help!

Answer 1

It looks correct.

The code should look for implementations of this method (through the Java Search Engine API) and accordingly rename the overriding methods as part of that same refactoring.

Answer 2

Thanks Gosu!

But this works for me!

RenameMethodProcessor processor = new RenameVirtualMethodProcessor(method);
        processor.setNewElementName(newName);
        processor.setUpdateReferences(true);

        RenameRefactoring refactoring = new RenameRefactoring(processor);


        refactoring.checkAllConditions(new NullProgressMonitor());
        Change res = refactoring.createChange(new NullProgressMonitor());

        res.perform(new NullProgressMonitor());
