template class OptionHandlerAdap0<typename C, typename R> : OptionHandler

Option handler adapter template.

This template creates an option handler for instances of class C by using a parameterless member function that return a value of type R. Also a template OptionHandlerAdap1 exists that could be used for member functions with one parameter.

Instead of explicitly instantiating the adapter templates, a convenience function exists that creates an option handler from a member function on the fly: 

template<typename C, typename R> 
      inline OptionHandler<C>* option (const string& id, bool consuming, R (C::*func) ());

template<typename C, typename R, typename A> 
      inline OptionHandler<C>* option (const string& id, bool consuming, R (C::*func) (A), A arg);




Public Members:
    OptionHandlerAdap0 (const string& id, bool consuming, MemFunc0 func) ;
    Creates an option handler adapter instance.
    If an option with name id is found in the argument list, member function func will be used to handle the option.

    virtual ArgVector::iterator fireOption (C& inst, const string& id, ArgVector& args, ArgVector::iterator rest) ;
    An option is handled.
    When an option id is found, member function func is applied to the inst of class C. No further parameters are consumed, so rest is returned unchanged.
