Description copied from interface: Command

This method allows to create new clone of a command, so the instances in the CommandManager's catalogs are masters, and the execution always uses clone created by this method.
NOTE: CommandsManager clone the command instances by standard Java cloning mechanism. If deep copy is needed then you have to override clone method of command.

Specified by:

clone in interface Command

Overrides:

clone in class Object

Throws:

CloneNotSupportedException
