Detailed Description

Implementations of set_number_of_grid_points.

Specializations may be trivial, meaning the object is similar to a double and doesn't actually represent grid data. The only requirement for trivial specializations is defining is_trivial as true.

Non-trivial specializations must define is_trivial to false, and must define a static apply function with the signature shown in the below example. Non-trivial specializations must also be accompanied by a specialization of the MakeWithValueImpls::NumberOfPoints struct. The apply function will only be called if the current size is incorrect, so implementations should not check the current size.

  static constexpr bool is_trivial = false;
  static void apply(const gsl::not_null<Resizable*> result, const size_t size) {
    result->size = size;
    result->resized = true;
  }
};
