#include <vtkDataReader.h>
Inheritance diagram for vtkDataReader:
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.

Specify the vtkCharArray to be used when reading from a string. If set, this array has precendence over InputString. Use this instead of InputString to avoid the extra memory copy. It should be noted that if the underlying char* is owned by the user ( vtkCharArray::SetArray(array, 1); ) and is deleted before the reader, bad things will happen during a pipeline update. |
