int ReadMeshSimple(VTK_FILEPATH const std::string &, vtkDataObject *) override
Overridden with default implementation of doing nothing so that subclasses only override what is need...
a dataset that is topologically regular with variable spacing in the three coordinate directions ...
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Store vtkAlgorithm input/output information.
abstract class to specify dataset behavior
Definition: vtkDataSet.h:52
virtual vtkDataObject * CreateOutput(vtkDataObject *currentOutput)
This can be overridden by a subclass to create an output that is determined by the file being read...
class to read any type of vtk dataset
concrete dataset represents vertices, lines, polygons, and triangle strips
Definition: vtkPolyData.h:79
static vtkDataReader * New()
helper superclass for objects that read vtk data files
Definition: vtkDataReader.h:43
virtual int FillOutputPortInformation(int port, vtkInformation *info)
Fill the output port information objects for this algorithm.
a simple class to control print indentation
Definition: vtkIndent.h:28
virtual int ReadMetaDataSimple(VTK_FILEPATH const std::string &, vtkInformation *)
A subclass can override this method to provide meta data specific to a particular file...
dataset represents arbitrary combinations of all possible cell types
#define VTK_FILEPATH
A subclass of ImageData.
topologically regular array of data
general representation of visualization data
Definition: vtkDataObject.h:54
