Test 2 types of methods

Maybe sometimes, we need to test whether 2 types are the same, Well, there are several ways. You can refer to the following:

1. Use TypeID, perhaps this is the most common method:

Template

Struct Same_Type

{

PUBLIC:

Operator bool ()

{

Return TypeId (t ()) == TypeId (u ());

}

}

2, use template to transit:

Template

Struct Same_Type

{

Private:

Template

Struct in

{enum {value = false};

Template <>

Struct in

{enum {value = true};

PUBLIC:

Enum {value = in :: value};

}

3, use the Typelist inside the Loki library:

Template

Struct Same_Type

{

PUBLIC:

Operator bool ()

{

Return Loki :: IndexOf == 0;

}

}

嗬嗬, of course, there is also something else to share together :)
