Tool< RET, ERR > Class Template Reference

#include "lib/visitor.hpp"

Description

template<typename RET = void, template< class > class ERR = UseDefault>
class lib::visitor::Tool< RET, ERR >

Marker interface / base class for all "visiting tools".

When applying such a tool to some concrete instance derived from Visitable, a special function treating this concrete subclass will be selected on the concrete visiting tool instance.

Definition at line 98 of file visitor.hpp.

	Tool function invocation return type.
using	ToolBase = Tool
	for templating the Tag and Dispatcher

Public Member Functions
