Constructor & Destructor Documentation

Singleton() [1/2]

template<typename Derived>

uniot::Singleton< Derived >::Singleton ( const Singleton< Derived > & )

delete

Copy constructor is deleted to prevent duplicating the singleton instance.

Singleton() [2/2]

template<typename Derived>

uniot::Singleton< Derived >::Singleton ( )

protecteddefault

Default constructor is protected to prevent instantiation outside of derived classes.

Derived classes should declare Singleton as a friend class to allow instantiation while keeping their constructors protected or private.

~Singleton()

template<typename Derived>

uniot::Singleton< Derived >::~Singleton ( )

protecteddefault

Default destructor is protected to prevent deletion through base class pointer.

Member Function Documentation

getInstance()

template<typename Derived>

static Derived & uniot::Singleton< Derived >::getInstance ( )

inlinestatic

Gets the singleton instance of the derived class.

This method creates the instance on first call (lazy initialization) and returns a reference to it on all subsequent calls. The instance is created as a static variable, ensuring thread-safe initialization in C++11 and above.

Return values

Derived&

Reference to the singleton instance of the derived class

operator=()

template<typename Derived>

Singleton & uniot::Singleton< Derived >::operator= ( const Singleton< Derived > & )

delete

Assignment operator is deleted to prevent duplicating the singleton instance.
