Bug 76926

Description Paul Hammant 2004-10-25 08:08:17 EDT

This is a new refactoring operation.

Notes - 
  SDI = Setter Depenency Injection
  CDI = Constructor Depenency Injection
Both as defined in http://www.martinfowler.com/articles/injection.html 

A member variable/field can have a Constructor Dependency Injection parameter
added for it. The Constructors can be changed en masse, or duplicated. Field can
optionally go final. Consider:

class Apple {
  final Orange orange;
  Banana banana;
  public Apple(Orange o) {
    orange = o;
  }
  public Apple() {
    orange = new DefaultOrange();
  }
}

if banana were selected, and the 'add CDI parameter to ctor' were actioned, the
result would be:

class Apple {
  final Orange orange;
  final Banana banana;
  public Apple(Orange o, Banana banana) {
    orange = o;
    this.banana = banana;
  }
  public Apple(Banana banana) {
    orange = new DefaultOrange();
    this.banana = banana;
  }
}
