Boost.Flyweight
Tags reference
A tag is a type of the form
tag<T> for some arbitrary
T.
In the context of Boost.Flyweight, tags are syntactic artifacts used
to differentiate instantiations of the class template
flyweight which would
otherwise be identical. Tagging a flyweight instantiation with
a tag type local to a given context ensures that the global resources
of that instantiation (for instance, the associated
factory class) will not be unintentionally
shared by other areas of the program.
"boost/flyweight/tag.hpp" synopsisnamespace boost{ namespace flyweights{ template<typename T> struct tag; } // namespace boost::flyweights } // namespace boost
tag
For any type T, tag<T> is a suitable
tag for use in instantiations of
flyweight.
