static vtkGraphAlgorithm * New()
Wrapper around std::string to keep symbols short.
Definition: vtkStdString.h:40
Store vtkAlgorithm input/output information.
Superclass for algorithms that produce only graph as output.
Base class for graph data types.
Definition: vtkGraph.h:287
a simple class to control print indentation
Definition: vtkIndent.h:39
virtual int RequestDataObject(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
This is called by the superclass.
Store zero or more vtkInformation instances.
reads vtkGraph data from a DIMACS formatted file
