Detailed Description
QAbstractFunctor is an abstract base class for all functors.
The QAbstractFunctor is used as a base class for all functors and data generators in Qt3DRender module.
When user defines a new functor or generator, they need to implement the QAbstractFunctor::id() method, which should be done using the QT3D_FUNCTOR macro in the class definition.

Desctructor
const T *QAbstractFunctor::functor_cast(const QAbstractFunctor *other) const
This method is used to cast functor other to type T if the other is of type T (or of subclass); otherwise returns 0. This method works similarly to QObject::qobject_cast, except with functors derived from QAbstractFunctor.
Warning: If T was not declared with QT3D_FUNCTOR macro, then the results are undefined.
