QT3D_FUNCTOR ( Class )

详细描述

QAbstractFunctor is an abstract base class for all functors.

QAbstractFunctor is used as a base class for all functors and data generators in Qt3DRender 模块。

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.

[default] QAbstractFunctor:: QAbstractFunctor ()

Default constructs an instance of QAbstractFunctor.

[virtual] QAbstractFunctor:: ~QAbstractFunctor ()

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 .

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