Class Ase::Persistent

template <class Class>

#include <cxxaux.hh>

Public Functions

Type	Name
constexpr	Persistent () noexcept A constexpr constructor avoids the static initialization order fiasco.
	operator bool () const Check if `this` stores a`Class` instance yet.
Class &	operator* () Retrieve reference to `Class` instance, always returns the same reference.
Class *	operator-> () Retrieve pointer to `Class` instance, always returns the same pointer.

Detailed Description

Create an instance of Class on demand that is constructed and never destructed. Due to its constexpr ctor and on-demand creation of Class, a Persistent<> can be accessed at any time during the static ctor (or dtor) phases and will always yield a properly initialized Class.
