All Implemented Interfaces:

Configurable, Contextualizable

public class SuperCloneCheck
extends AbstractSuperCheck

Checks that an overriding clone() method invokes super.clone(). Does not check native methods, as they have no possible java defined implementation.

Reference: Object.clone().

To configure the check:

 <module name="SuperClone"/>
 

Example:

 class A {

  public Object clone() { // OK
   return super.clone();
  }
 }

 class B {
 private int b;

  public B clone() { // violation, does not call super.clone()
   B other = new B();
   other.b = this.b;
   return other;
  }
 }

 class C {

  public C clone() { // OK
   return (C) super.clone();
  }
 }
