fwCom::util::WeakCall< T, R > Struct Template Reference

Weak functor class. Store a zero-arg-function and a weak pointer on an object. The WeakCall is callable only once. A bad_weak_ptr exception is thrown if the weak_ptr is expired when operator() is called A fwCom::exception::WorkerChanged exception is thrown if the target slot worker changed since weakcall request.

Detailed Description

template<typename T, typename R>
struct fwCom::util::WeakCall< T, R >

Weak functor class. Store a zero-arg-function and a weak pointer on an object. The WeakCall is callable only once. A bad_weak_ptr exception is thrown if the weak_ptr is expired when operator() is called A fwCom::exception::WorkerChanged exception is thrown if the target slot worker changed since weakcall request.

Template Parameters

T	Stored object type.
R	Stored function return type.
