Extern Template

Extern Template - Instead, extern template allows developers to choose a single translation unit in which to explicitly generate object code for all the definitions pertaining to that specific template specialization as. If you know the finite set of types your template class/function is going to be used for,. An explicit instantiation declaration (an extern template) skips implicit instantiation step: #include myvector.h extern template class myvector; A template specialization can be explicitly declared as a way to suppress multiple instantiations. Reducing compile times by using extern template is a project scope strategy. In a template declaration, extern specifies that the template has already been instantiated elsewhere. Extern tells the compiler it can reuse the other instantiation, rather than. There are several reasons why extern templates are not commonly declared in header files and then explicitly instantiated in the cpp files. It results in the implicit instantiation of the class as well as that of any nested classes.

In c++11 we've got template explicit. One potential use for this is creating a shared library. My goal is to compile some instanciations if foo<> in a seperate compilation unit in order to save. One should consider which are the templates most expensive that are used in many translation. It results in the implicit instantiation of the class as well as that of any nested classes. An explicit instantiation declaration (an extern template) skips implicit instantiation step: I am trying to understand extern templates, but i can't get it to work. Using extern templates thus reduces both. In c++11, extern template is added to reduce compile time and object size by telling compiler not to instantiate template function or class. What is extern template in c++?

The Code That Would Otherwise Cause An Implicit Instantiation Instead Uses The Explicit.

If you know the finite set of types your template class/function is going to be used for,. There are several reasons why extern templates are not commonly declared in header files and then explicitly instantiated in the cpp files. An extern template allows you to declare a template without instantiating it in the translation unit. One potential use for this is creating a shared library.
