Interface AnnotationViewInfoInterface

The AnnotationViewInfoInterface interface is used to store the annotations properties linked to a part instance.

Please see Annotations for more explanations about annotations.

The AnnotationViewInfoInterface is retrieved when using a getAnnotationViews i.e. when the metadata attached to a part instance are retrieved from an id card request.

The actual data will be retrieved by using an AnnotationGetterInterface since the AnnotationViewInfoInterface only stores general properties of an annotation view, but not the annotation view internal data.
