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.

Reimplemented in vtkBridgeAttribute.

virtual int vtkGenericAttribute::IsA

(

const char *

name

)

[virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
