In this section the basic syntactic constructions for declaring templates
|
|
are summarized. When em(defining) templates, the terminating
|
|
semicolon should be replaced by a function body.
|
|
|
|
Not every template declaration may be converted into a template definition. If
|
|
a definition may be provided it is explicitly mentioned.
|
|
itemization(
|
|
it() A plain template declaration (a definition may be provided):
|
|
verb(
|
|
template <typename Type1, typename Type2>
|
|
void function(Type1 const &t1, Type2 const &t2);
|
|
)
|
|
it() A template instantiation declaration (no definition may be provided):
|
|
verb(
|
|
template
|
|
void function<int, double>(int const &t1, double const &t2);
|
|
)
|
|
it() A template using explicit types (no definition may be provided):
|
|
verb(
|
|
void (*fp)(double, double) = function<double, double>;
|
|
void (*fp)(int, int) = function<int, int>;
|
|
)
|
|
it() A template explicit specialization (a definition may be provided):
|
|
verb(
|
|
template <>
|
|
void function<char *, char *>(char *const &t1, char *const &t2);
|
|
)
|
|
it() A template declaration declaring friend function templates within
|
|
hi(class template: friend function template) class templates (covered
|
|
in section ref(TEMPFRIENDS), no definition may be provided):
|
|
verb(
|
|
friend void function<Type1, Type2>(parameters);
|
|
)
|
|
)
