Superclass for all pipeline executives in VTK.
vtkExecutive is the superclass for all pipeline executives in VTK. A VTK executive is responsible for controlling one instance of vtkAlgorithm. A pipeline consists of one or more executives that control data flow. Every reader, source, writer, or data processing algorithm in the pipeline is implemented in an instance of vtkAlgorithm.

vtkAlgorithm* vtkExecutive::GetAlgorithm | ( | ) |
Get the algorithm to which this executive has been assigned.
|

Generalized interface for asking the executive to fulfill pipeline requests.
Reimplemented in vtkThreadedStreamingPipeline, vtkStreamingDemandDrivenPipeline, and vtkDemandDrivenPipeline.
|
virtual |
A special version of ProcessRequest meant specifically for the pipeline modified time request. This is an optimization since the request is called so often and it travels the full length of the pipeline. We augment the signature with method arguments containing the common information, specifically the output port through which the request was made and the resulting modified time. Note that unlike ProcessRequest the request information object may be NULL for this method. It also does not contain a request identifcation key because the request is known from the method name.
Reimplemented in vtkDemandDrivenPipeline.

void vtkExecutive::SetSharedInputInformation | ( | vtkInformationVector ** | inInfoVec | ) |
Get the output port that produces the given data object. Works only if the data was producer by this executive's algorithm. virtual vtkAlgorithmOutput* GetProducerPort(vtkDataObject*);
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.
