QT3D_FUNCTOR ( Class )

詳細描述

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 模塊。

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.

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.

QT3D_FUNCTOR ( Class )

This macro assigns functor id to the Class , which is used by QAbstractFunctor::functor_cast to determine if the cast can be done.
