const_iterator end

(

)

const

The C++ iterator set to the end of this GestureList.

Leap::GestureList gestures = frame.gestures();
for(Leap::GestureList::const_iterator gl = gestures.begin(); gl != gestures.end(); gl++)
    std::cout << (*gl).toString() << std::endl;

bool isEmpty

(

)

const

Reports whether the list is empty.

if (!frame.gestures().isEmpty()) {
    //Handle this frame's gesture objects
}

Returns
