Description

template<template< typename... > class Base, typename Derived>
struct is_derived_from_template< Base, Derived >

Helper template which uses function overloading and implict up-casting to determine whether or not a class is derived from a templated base class (i.e. MapdataPointInfoAccessor derives from MapdataAccessorBase). See: https://en.cppreference.com/w/cpp/language/sfinae.
