Detailed Description

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.

Member Function Documentation

[virtual] QAbstractFunctor::~QAbstractFunctor()

Desctructor

const T *QAbstractFunctor::functor_cast(const Qt3DRender::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_cast(), except with functors derived from QAbstractFunctor.

Warning: If T was not declared with QT3D_FUNCTOR macro, then the results are undefined.

[pure virtual] qintptr QAbstractFunctor::id() const

Returns a pointer to the id of the functor.
