\since 5.7
\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 Qt3DRender 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.
*/
/*!
\fn qintptr QAbstractFunctor::id() const
*/
/*!
\macro QT3D_FUNCTOR(Class)
\relates Qt3DRender::QAbstractFunctor
This macro assigns functor id to the \a Class, which is used by QAbstractFunctor::functor_cast
to determine if the cast can be done.
*/
/*!
\fn const T *QAbstractFunctor::functor_cast(const QAbstractFunctor *other) const
This method is used to cast functor \a other to type T if the other is of
type T (or of subclass); otherwise returns 0. This method works similarly
to \l QObject::qobject_cast, except with functors derived from QAbstractFunctor.
\warning If T was not declared with \l QT3D_FUNCTOR macro, then the results are undefined.
