Rule:  TypeResolution2Checked automatically with code checker

This rule is Obsolete
Synopsis:clone() method should be implemented only if implementing Cloneable interface
Language:Java
Severity Level:2
Category:TypeResolution


Description:
The method clone() should only be implemented if the class implements the Cloneable interface with the exception of a final method that only throws CloneNotSupportedException. This version uses PMD's type resolution facilities, and can detect if the class implements or extends a Cloneable class
public class MyClass {
 public Object clone() throws CloneNotSupportedException {
  return foo;
 }
}
