Detailed Description

Visitor to support creating a CommandImpl clone.

Created and managed by CommandRegistry, on clone creation an instance of this builder object is passed down to re-gain a fully typed context, necessary for re-wiring the undo functors and the memento storage within the cloned parts.

template<typename ARG>

void control::CommandImplCloneBuilder::buildCloneContext ( ARG const & origArgHolder ) [inline]

to be executed from within the specifically typed context of a concrete command ArgumentHolder; allocate a clone copy and then prepare a new UNDO-Functor, which is correctly wired with the memento holder within this new clone closure.

After that point, these prepared parts can be retrieved through the public accessor functions; they will be used by the command registry to put together a complete clone copy of the original CommandImpl.
