public HardSigmoidFunction clone()
Objectclass and removes the exception that it throws. Its default behavior is to automatically create a clone of the exact type of object that the clone is called on and to copy all primitives but to keep all references, which means it is a shallow copy. Extensions of this class may want to override this method (but call
super.clone()to implement a "smart copy". That is, to target the most common use case for creating a copy of the object. Because of the default behavior being a shallow copy, extending classes only need to handle fields that need to have a deeper copy (or those that need to be reset). Some of the methods in
ObjectUtilmay be helpful in implementing a custom clone method. Note: The contract of this method is that you must use
super.clone()as the basis for your implementation.
