Detailed Description

template<typename R, typename... Args>
class CoreFunction< R(Args...)>

Simplified version of the std::function object.

This can be used to store a lambda or any "callable" thing. It's used like std::function: ``` CoreFunction<bool (int)> function = [] (int a) { return (a % 2) == 0; }; function(3); ```

Note that like std::function, you need to be carefull with the lifetime of what you pass to it. For instance if you create a CoreFunction from a lambda, make sure that if the lambda captures stuff, you capture either by value, or that the reference captured objects won't be destoyed before the function is used.

Constructor & Destructor Documentation

template<typename R , typename... Args>

CoreFunction< R(Args...)>::CoreFunction ( void  )

inline

Default constructor. Calling a CoreFunction initialized like this is undefined behavior! (e.g. will probably crash)

template<typename R , typename... Args>

template<typename Functor >

CoreFunction< R(Args...)>::CoreFunction ( const Functor &  functor )

inline

Construct an instance from a "functor" (basically any callbale thing: a pointer to a static function, lambda, function object, etc.)

Parameters

functor

The functor. Needs to have a copy constructor and a move constructor.

Member Function Documentation

template<typename R , typename... Args>

template<typename Functor >

CoreFunction< R(Args...)> & CoreFunction< R(Args...)>::operator= ( const Functor &  functor )

inline

Assign a function object.

Parameters

functor

The function object. Can be a lambda, pointer to function, etc.
