++ \brief QAbstractFunctor is an abstract base class for all functors.
++
++ The QAbstractFunctor is used as a base class for all functors and data
++ generators in Qt3DCore module.
++
++ When user defines a new functor or generator, they need to implement the
++ \l QAbstractFunctor::id() method, which should be done using the \c {QT3D_FUNCTOR}
++ macro in the class definition.

++ This method is used to cast functor \a other to type T if the other is of

++ to \l [QtCore] {qobject_cast(const QObject *object)}{qobject_cast()},
++ except with functors derived from QAbstractFunctor.
++
++ \warning If T was not declared with \l QT3D_FUNCTOR macro, then the results are undefined.
