CloneMethodMustImplementCloneable

CloneMethodMustImplementCloneable

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.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.typeresolution.rules.CloneMethodMustImplementCloneable
Example(s):


            
public class MyClass {
	public Object clone() throws CloneNotSupportedException {
		return foo;
	}
}
