Detailed Description

abstract class defined API for attribute data

vtkGenericAttribute is an abstract class that defines an API for attribute data. Attribute data is data associated with the topology or geometry of a dataset (i.e., points, cells, etc.). vtkGenericAttribute is part of the adaptor framework (see GenericFiltering/README.html).

vtkGenericAttribute provides a more general interface to attribute data than its counterpart vtkDataArray (which assumes a linear, contiguous array). It adopts an iterator interface, and allows attributes to be associated with points, edges, faces, or edges.
