EnableIf And PerfectForwarding With Templated Constructors - GerdHirsch/Cpp-TemplateBasics GitHub Wiki
This Project demonstrates the usage of templated constructors, std::enabel_if<..> and perfect forwarding with std::forward<..>.
class Base
has two Member
m1
and m2
and a templatized constructor which has
two forwarding reference parameters of Member&&
. The third parameter is a dummy parameter
to enable SFINAE with enableForMembersOnly
based on std::enable_if
to which it
delegates via inheritance.
There is a talk about this stuff from Nicolai Josuttis at cppcon 2017.
