Question

Consider a wrapper class W, wrapping C, this meaning that for most attributes of C, there is a correspondent attribute A on W, its logic consisting in nothing more than delegation to C‘s A. This situation can be most precisely depicted with the sketch shown below:

class W {
    private C c;

    getX() { return c.getX(); }
    getY() { return c.getY(); }
}

The trouble is that I’ve decided that I wan’t to get rid of getX(), and I’d prefer to either as a transitory step to put C c as public, having all the calling code of W do a w.c.getX() or w.c.getY() or alternatively to put create a W.getC(), and have all calls to getX() and getY() go through it.

What this all boils down is to an “un-encapsulate” refactoring. Is there anything performing this much needed task either in Eclipse or Intellij?

Answer 1

1. Write your new getC() method.
2. Rewrite getX() to be return getC().getX().
3. Inline getX().

The same goes for y.
