int ReadMeshSimple(VTK_FILEPATH const std::string &, vtkDataObject *) override
Overridden with default implementation of doing nothing so that subclasses only override what is need...
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Store vtkAlgorithm input/output information.
virtual vtkDataObject * CreateOutput(vtkDataObject *currentOutput)
This can be overridden by a subclass to create an output that is determined by the file being read...
Base class for graph data types.
Definition: vtkGraph.h:295
static vtkDataReader * New()
read vtkGraph data file
helper superclass for objects that read vtk data files
Definition: vtkDataReader.h:54
virtual int FillOutputPortInformation(int port, vtkInformation *info)
Fill the output port information objects for this algorithm.
a simple class to control print indentation
