Detailed Description

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.

static int vtkExecutive::IsTypeOf ( const char * type )

static

virtual int vtkExecutive::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkCompositeDataPipeline, vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, vtkThreadedCompositeDataPipeline, vtkCachedStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

void vtkExecutive::PrintSelf	(	ostream &	os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

Reimplemented in vtkStreamingDemandDrivenPipeline, and vtkThreadedCompositeDataPipeline.

Get the algorithm to which this executive has been assigned.

virtual int vtkExecutive::ProcessRequest	(	vtkInformation *	request,

Reimplemented in vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

		vtkInformationVector **	inInfoVec,
		vtkInformationVector *	outInfoVec,
		int	requestFromOutputPort,
		vtkMTimeType *	mtime
	)

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.
