I have a simple design question:

assume you have two variables in a class, e.g.

[pseudocode]

class MyObject {

   String a;
   String b;

   function setA() {

   }

   function getA() {

   }

    function setB() {

   }

   function getB() {

  }

}

Assume that the getter & setter are not just simple getter & setter ,
there are some algorithms inside, but the algorithms are the same for
a & b (but apply to different variable - a & b), so we are duplicating
codes in the above example, i.e. in setA and setB

so should we do something like?

function set(target, value) {
   // do the common stufft
   target = value;
}

function setA(value) {
  this.set( this.a, value );
}

function setB(value) {
  this.set( this.b, value );
}

do you think this design is good?

thanks.
