general representation of visualization data
Definition: vtkDataObject.h:64
helper superclass for objects that read vtk data files
Definition: vtkDataReader.h:44
class to read any type of vtk dataset
vtkDataSet * GetOutput(int idx)
Get the output of this filter.
vtkPolyData * GetPolyDataOutput()
Get the output as various concrete types.
~vtkDataSetReader() override
vtkStructuredPoints * GetStructuredPointsOutput()
Get the output as various concrete types.
static vtkDataSetReader * New()
int ReadMetaDataSimple(VTK_FILEPATH const std::string &fname, vtkInformation *metadata) override
Read metadata from file.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkUnstructuredGrid * GetUnstructuredGridOutput()
Get the output as various concrete types.
vtkDataSet * GetOutput()
Get the output of this filter.
virtual int ReadOutputType()
This method can be used to find out the type of output expected without needing to read the whole fil...
int FillOutputPortInformation(int, vtkInformation *) override
Fill the output port information objects for this algorithm.
vtkRectilinearGrid * GetRectilinearGridOutput()
Get the output as various concrete types.
vtkStructuredGrid * GetStructuredGridOutput()
Get the output as various concrete types.
int ReadMeshSimple(VTK_FILEPATH const std::string &fname, vtkDataObject *output) override
Actual reading happens here.
vtkDataObject * CreateOutput(vtkDataObject *currentOutput) override
This can be overridden by a subclass to create an output that is determined by the file being read.
