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;
  }
}

Use the following options to configure the inspection:

Whether to only report setter calls on this, not on objects of the same type passed in as a parameter.
Whether to ignore non-private setters.

Inspection options

Option	Type	Default
Ignore setter calls on other objects	Checkbox	false
Only report when setter is 'private'	Checkbox	false
