To create an instance of class vtkExecutive, simply invoke its constructor as follows
obj = vtkExecutive
obj
is an instance of the vtkExecutive class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkExecutive = obj.NewInstance ()
vtkExecutive = obj.SafeDownCast (vtkObject o)
vtkAlgorithm = obj.GetAlgorithm ()
- Get the algorithm to which this executive has been assigned.
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.
int = obj.GetNumberOfInputPorts ()
- Get the number of input/output ports for the algorithm associated
with this executive. Returns 0 if no algorithm is set.
int = obj.GetNumberOfOutputPorts ()
- Get the number of input/output ports for the algorithm associated
with this executive. Returns 0 if no algorithm is set.
int = obj.GetNumberOfInputConnections (int port)
- Get the number of input connections on the given port.
vtkInformation = obj.GetOutputInformation (int port)
- Get the pipeline information object for the given output port.
vtkInformationVector = obj.GetOutputInformation ()
- Get the pipeline information object for all output ports.
vtkInformation = obj.GetInputInformation (int port, int connection)
- Get the pipeline information for the given input connection.
vtkInformationVector = obj.GetInputInformation (int port)
- Get the pipeline information vectors for the given input port.
vtkExecutive = obj.GetInputExecutive (int port, int connection)
- Get the executive managing the given input connection.
vtkDataObject = obj.GetOutputData (int port)
- Get/Set the data object for an output port of the algorithm.
obj.SetOutputData (int port, vtkDataObject , vtkInformation info)
- Get/Set the data object for an output port of the algorithm.
obj.SetOutputData (int port, vtkDataObject )
- Get/Set the data object for an output port of the algorithm.
vtkDataObject = obj.GetInputData (int port, int connection)
- Get the data object for an input port of the algorithm.
vtkAlgorithmOutput = obj.GetProducerPort (vtkDataObject )
- Get the output port that produces the given data object.
obj.SetSharedOutputInformation (vtkInformationVector outInfoVec)
- Set a pointer to an outside instance of input or output
information vectors. No references are held to the given
vectors, and setting this does not change the executive object
modification time. This is a preliminary interface to use in
implementing filters with internal pipelines, and may change
without notice when a future interface is created.
obj.Register (vtkObjectBase o)
- Participate in garbage collection.
obj.UnRegister (vtkObjectBase o)
- Participate in garbage collection.
