To create an instance of class vtkDemandDrivenPipeline, simply invoke its constructor as follows
obj = vtkDemandDrivenPipeline
obj
is an instance of the vtkDemandDrivenPipeline class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkDemandDrivenPipeline = obj.NewInstance ()
vtkDemandDrivenPipeline = obj.SafeDownCast (vtkObject o)
int = obj.Update ()
- Bring the algorithm's outputs up-to-date. Returns 1 for success
and 0 for failure.
int = obj.Update (int port)
- Bring the algorithm's outputs up-to-date. Returns 1 for success
and 0 for failure.
long = obj.GetPipelineMTime ()
- Get the PipelineMTime for this exective.
int = obj.SetReleaseDataFlag (int port, int n)
- Set whether the given output port releases data when it is
consumed. Returns 1 if the the value changes and 0 otherwise.
int = obj.GetReleaseDataFlag (int port)
- Get whether the given output port releases data when it is consumed.
int = obj.UpdatePipelineMTime ()
- Bring the PipelineMTime up to date.
int = obj.UpdateDataObject ()
- Bring the output data object's existence up to date. This does
not actually produce data, but does create the data object that
will store data produced during the UpdateData step.
int = obj.UpdateInformation ()
- Bring the output information up to date.
int = obj.UpdateData (int outputPort)
- Bring the output data up to date. This should be called only
when information is up to date. Use the Update method if it is
not known that the information is up to date.
