general representation of visualization data
helper superclass for objects that read vtk data files
Definition: vtkDataReader.h:55
class to read any type of vtk data object
vtkDataObject * CreateOutput(vtkDataObject *currentOutput) override
This can be overridden by a subclass to create an output that is determined by the file being read.
vtkPolyData * GetPolyDataOutput()
Get the output as various concrete types.
virtual int ReadOutputType()
This method can be used to find out the type of output expected without needing to read the whole fil...
static vtkGenericDataObjectReader * New()
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int ReadMeshSimple(VTK_FILEPATH const std::string &fname, vtkDataObject *output) override
Actual reading happens here.
vtkStructuredPoints * GetStructuredPointsOutput()
Get the output as various concrete types.
int ReadMetaDataSimple(VTK_FILEPATH const std::string &fname, vtkInformation *metadata) override
Read metadata from file.
vtkDataObject * GetOutput(int idx)
Get the output of this filter.
vtkGraph * GetGraphOutput()
Get the output as various concrete types.
vtkStructuredGrid * GetStructuredGridOutput()
Get the output as various concrete types.
int FillOutputPortInformation(int, vtkInformation *) override
Fill the output port information objects for this algorithm.
vtkTable * GetTableOutput()
Get the output as various concrete types.
~vtkGenericDataObjectReader() override
vtkTree * GetTreeOutput()
Get the output as various concrete types.
vtkRectilinearGrid * GetRectilinearGridOutput()
Get the output as various concrete types.
vtkDataObject * GetOutput()
Get the output of this filter.
vtkMolecule * GetMoleculeOutput()
Get the output as various concrete types.
vtkUnstructuredGrid * GetUnstructuredGridOutput()
Get the output as various concrete types.
Base class for graph data types.
Definition: vtkGraph.h:339
