Detailed Description

helper superclass for objects that read vtk data files

vtkDataReader is a helper superclass that reads the vtk data file header, dataset type, and attribute data (point and cell attributes such as scalars, vectors, normals, etc.) from a vtk data file. See text for the format of the various vtk file types.

virtual int vtkDataReader::ProcessRequest ( vtkInformation request,
vtkInformationVector **  inInfo,

) [protected, virtual]

Upstream/Downstream requests form the generalized interface through which executives invoke a algorithm's functionality. Upstream requests correspond to information flow from the algorithm's outputs to its inputs. Downstream requests correspond to information flow from the algorithm's inputs to its outputs. A downstream request is defined by the contents of the request information object. The input to the request is stored in the input information vector passed to ProcessRequest. The results of an downstream request are stored in the output information vector passed to ProcessRequest. An upstream request is defined by the contents of the request information object. The input to the request is stored in the output information vector passed to ProcessRequest. The results of an upstream request are stored in the input information vector passed to ProcessRequest. It returns the boolean status of the pipeline (false means failure).
