Class StrictCloneabilityTestSupport<T extends Cloneable>

public abstract class StrictCloneabilityTestSupport<T extends Cloneable>
extends Object

Support structure for testing the cloneability of instances of a class. The contract for Object.clone() is fairly lax, but this class tests that after a clone operation, the original and the clone references refer to instances of the same class, and are not the same, and compare equal, and whose respective reference fields do not refer to the same objects. For reference fields that are arrays, Lists, or Maps, tests also that each element of the original collection does not refer to the same object as the corresponding slot in the clone (values only for maps, since keys of maps should be immutable).
