Detailed Description

interface wrapper around utility::signals::LinkUnit

Can be used to manage the link between Subject and Observer. Signals can be temporarily blocked and the connection can be invalidated (disconnected) by the user. If a Subject is destroyed or a manual disconnect is called via the SignalHub, the Link will automatically become invalidated.

Remarks:

Returned by utility::signals::SignalHub upon connection.
