Re: [Dev-C++] More Template Problems -- NewB

[Abdelkader G. <go...@li...>]

it's just a small problem with the type that you have declared: 

> typedef jme::Index<const int, const std::string > T_index;

So, T_index now is considered as an alias to the type jme::Index<const int, 
const std::string >

Consequently, accessing an attribute or a method that are not declared as 
static for this class has no sense. Perhaps you intention was to declare a 
variable which is an instance of T_index. In this case you should write 
this:
<old     code> T_index( i, name );
<correct code> T_index my_instance(i,name);
                       ^^^^^^^^^^^
and change also this:

<old     code> std::cout << T_index.getKey() << std::endl;
<correct code> std::cout << my_instance.getKey() << std::endl;
                            ^^^^^^^^^^^
Kind regards,
