| 14 | \brief QAbstractFunctor is an abstract base class for all functors. |
|---|
| 15 | |
|---|
| 16 | The QAbstractFunctor is used as a base class for all functors and data |
|---|
| 17 | generators in Qt3DCore module. |
|---|
| 18 | |
|---|
| 19 | When user defines a new functor or generator, they need to implement the |
|---|
| 20 | \l QAbstractFunctor::id() method, which should be done using the \c {QT3D_FUNCTOR} |
|---|
| 21 | macro in the class definition. |
