Let's cause implicit instantiations of the static data members now. int main A 1 c reference them.. translation unit is examined to produce a list of required instantiations. Note this may include instantiations which have been explicitly.. a list of required instantiations. Note this may include instantiations which have been explicitly requested 14.7.2 . The definitions..
Why does C++ compilation take so long? http://stackoverflow.com/questions/318398/why-does-c-compilation-take-so-long T is the only type that is compiled no matter how many instantiations of List you have in your program. In C vector int is a completely.. templates that create dozens and dozens of template instantiations. Templates may also result in extremely complex types with ridiculously..
Why does C++ not have reflection? http://stackoverflow.com/questions/359237/why-does-c-not-have-reflection simple template code tends to create quite a few template instantiations. The C standard library relies on this aggressive optimization...
Why can templates only be implemented in the header file? http://stackoverflow.com/questions/495021/why-can-templates-only-be-implemented-in-the-header-file ... Foo.cpp implementation of Foo's methods explicit instantiations template class Foo int template class Foo float You will only..
Where and why do I have to put the “template” and “typename” keywords? http://stackoverflow.com/questions/610245/where-and-why-do-i-have-to-put-the-template-and-typename-keywords names however may have different meaning in different instantiations of a template but unfortunately are not caught by this general..
Can standard container templates be instantiated with incomplete types? http://stackoverflow.com/questions/8329826/can-standard-container-templates-be-instantiated-with-incomplete-types this make the above constructs illegal even though the instantiations are not in block scope Does this fall under operations on types.. Or is a library implementation forbidden to incur template instantiations that might fail for incomplete types when all specifically required.. fail for incomplete types when all specifically required instantiations succeed Edit Since only functions may call and instantiate other..
“Undefined reference to” template class constructor http://stackoverflow.com/questions/8752837/undefined-reference-to-template-class-constructor cola float and cola string because those particular instantiations are used in main.cpp . The bad news is that the implementations.. . When compiling cola.cpp the compiler won't compile those instantiations either because there are no implicit or explicit instantiations.. either because there are no implicit or explicit instantiations of cola float or cola string . Remember when compiling cola.cpp..
When should I make explicit use of the `this` pointer? http://stackoverflow.com/questions/993352/when-should-i-make-explicit-use-of-the-this-pointer know how to treat i since it may or may not exist in all instantiations of A . In order to tell it that i is indeed a member of A T..
