Member Function Documentation

AttachObserver()

virtual bool imod::IModel::AttachObserver ( IObserver *  observerPtr )

pure virtual

Attaches model object to observer observerPtr.

Warning

Please note, that double call of this function for the same observer will cause an assertion.

Parameters

observerPtr

observer, cannot be NULL.

Implemented in imod::CModelBase, and imod::CModelProxy.

Referenced by imod::TSingleModelObserverBase< ModelInterface >::AttachOrSetObject(), iqt2d::TShapeParamsGuiCompBase< Ui, Shape, ShapeModel >::CreateShape(), and iqt2d::TShapeParamsGuiCompBase< Ui, Shape, ShapeModel >::OnModelAttached().

DetachAllObservers()

virtual void imod::IModel::DetachAllObservers ( )

pure virtual

Detaches all attached observers.

Implemented in imod::CModelBase, and imod::CModelProxy.

DetachObserver()

virtual void imod::IModel::DetachObserver ( IObserver *  observerPtr )

pure virtual

Detaches model object from observer observerPtr.

Warning

Please note, that call of this function for the observer which is not attached to the observer observer will cause an assertion. To prevent this, you can use the isAttached() function.

Implemented in imod::CModelBase, and imod::CModelProxy.

Referenced by iqt2d::TShapeParamsGuiCompBase< Ui, Shape, ShapeModel >::OnModelDetached().

IsAttached()

virtual bool imod::IModel::IsAttached ( const IObserver *  observerPtr ) const

pure virtual

Returns true if observer observer is attached to this model object.

Implemented in imod::CModelBase, and imod::CModelProxy.

Referenced by iqt2d::TShapeParamsGuiCompBase< Ui, Shape, ShapeModel >::OnModelDetached().
