Dispatcher< TAR, TOOL > Class Template Reference

#include "lib/visitor-dispatcher.hpp"

Description

template<class TAR, class TOOL>
class lib::visitor::Dispatcher< TAR, TOOL >

For each possible call entry point via some subclass of the visitable hierarchy, we maintain a dispatcher table to keep track of all concrete tool implementations able to receive and process calls on objects of this subclass.

Parameters

TAR	the concrete target (subclass) type within the visitable hierarchy
TOOL	the overall tool family (base class of all concrete tools)

Definition at line 109 of file visitor-dispatcher.hpp.
