Detailed Description

template<class T>
class albert::ExtensionWatcher< T >

Non-QObject extension registry observer.

Convenient tool to observe the extension registry for types you are interested in. Rationale: QObject does neither support templates nor abstract classes also each object must inherit only one QObject. Therefore this class does not use QObject.
