Detailed Documentation¶

Generic callback which uses bound class method as callable.

Use Make_callback for convenient instantiation. Specialized template version for class member function.

Parameters:

Class_ptr	Pointer to class object (used with pointer semantic, can be any smart pointer as well).
Class	method to call.
Args	Arguments pack.

Typedefs¶

typedef Callback_base<typename std::result_of<Method(Class_ptr, Args...)>::type> Base_type

Base class type.

typedef typename Base_type::template Ptr<Callback> Ptr

Callable pointer class type.

typedef typename std::tuple_element<arg_idx, Args_tuple>::type Arg_type

Get type of the specified argument.

Parameters:

arg_idx

Index of the argument. Should be in range [0, sizeof…(Args)).

Construction¶

Callback(Method method, Class_ptr&& obj_ptr, Args&&... args)

Constructor for class method bound callback.

Callback(Callback&&)

Move constructor.

Methods¶

static Ptr Create(Method method, Class_ptr&& obj_ptr, Args&&... args)

Create callback instance.

virtual Base_type::Result_t operator () ()

Execute callback.

template <size_t arg_idx>
Arg_type<arg_idx>& Get_arg()

Get reference to an argument at the specified position.

Template parameters:

arg_idx Index of the argument to get.

Returns:

Reference to the stored argument.
