clone
public Object clone()
throws CloneNotSupportedException
Description copied from class: Object
Creates and returns a copy of this Object. The default
implementation returns a so-called "shallow" copy: It creates a new
instance of the same class and then copies the field values (including
object references) from this instance to the new instance. A "deep" copy,
in contrast, would also recursively clone nested objects. A subclass that
needs to implement this kind of cloning should call super.clone()
to create the new instance and then create deep copies of the nested,
mutable objects.
- Overrides:
clone in class MessageDigestSpi
- Returns:
- a copy of this object.
- Throws:
CloneNotSupportedException - if this object's class does not implement the Cloneable interface.
