void vtkDemandDrivenPipeline::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

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.

virtual int vtkDemandDrivenPipeline::ProcessRequest	(	vtkInformation *	request,

Get whether the given output port releases data when it is consumed.

virtual int vtkDemandDrivenPipeline::UpdatePipelineMTime ( )

virtual

Bring the PipelineMTime up to date.

virtual int vtkDemandDrivenPipeline::UpdateDataObject ( )

virtual int vtkDemandDrivenPipeline::UpdateInformation ( )

virtual

Bring the output information up to date.

Reimplemented from vtkExecutive.

virtual int vtkDemandDrivenPipeline::UpdateData ( int outputPort )
