Call to simple setter from within class

Reports calls to a simple property setter from within the property's class.

A simple property setter is defined as one which simply assigns the value of its parameter to a field, and does no other calculations. Such simple setter calls can be safely inlined. Some coding standards also suggest against the use of simple setters for code clarity reasons.

Example:

  class Foo {
  private int index;
    public Foo(int idx) {
       setIndex(idx);
    }
    public void setIndex(int idx) {
       index = idx;
    }
  }

After the quick-fix is applied:

  class Foo {
    private int index;
    public Foo(int idx) {
      index = idx;
    }
    public void setIndex(int idx) {
      index = idx;
    }
  }
