RE: [Dev-C++] Is it possible - templates (.h and .cpp) ?

Well, I guess there is a keyword export(as given in Stroustrup's book) =
whose
purpose is exactly this(separate compilation strategy)..Though as far =
as I
know this is not supported by .NET and CodeWarrior.

Subject: Re: [Dev-C++] Is it possible - templates (.h and .cpp) ?

Hi,
    excuse me but I'm just a newbie in C++ (most of my developpements =
are
made in ANSI-C) but was curious about the subject and made some google
search and found this URL:=20
http://www.cplusplus.com/doc/tutorial/tut5-1.html. There, the author =
says at
the end the following:

/The macro-like functionality of templates, forces a restriction for
multi-file projects: the implementation (definition) of a template =
class or
function _must_ be in the same file as the declaration. That means we =
cannot
separate the interface in a separate header file and we must include =
both
interface and implementation in any file that uses the templates. /

/Going back to the library of functions, if we wanted to make a library =
of
function templates, instead of creating a header file (*.h*) we should
create a "template file" with both the interface and implementation of =
the
function templates (there is no convention on the extension for this =
type of
file other than there be no extension at all or to keep the .h). The
inclusion more than once of the same template file with both =
declarations
and definitions in a project doesn't generate linkage errors, since =
they are
compiled on demand and compilers that allow templates should be =
prepared to
not generate duplicate code in these cases. /




    Hope this helped.
