Class SuperCloneCheck

  • 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();
  }
 }
