What is the motivation of this connect?

QMetaObject::connect(obj, signalIndex, this, staticMetaObject.methodCount());

Hi.
Can you please explain what's the motivation of this connection? Especially I have trouble to understand the destination method index "methodCount()". Does this suppress the signal (because it points to a not existing method)?
Thank you.

It points to a not existing method, but that is then handled there:

property_bindings/src/property_qobject.h

Line 49 in 14c4f1a

notify();

since the qt_metacall is going to be called with that index.
