Detailed Description

Executive supporting partial updates.

vtkStreamingDemandDrivenPipeline is an executive that supports updating only a portion of the data set in the pipeline. This is the style of pipeline update that is provided by the old-style VTK 4.x pipeline. Instead of always updating an entire data set, this executive supports asking for pieces or sub-extents.

int vtkStreamingDemandDrivenPipeline::PropagateUpdateExtent ( int outputPort )

Propagate the update request from the given output port back through the pipeline. Should be called only when information is up to date.

static int vtkStreamingDemandDrivenPipeline::SetWholeExtent	(	vtkInformation *	,

static

Set/Get the whole extent of an output port. The whole extent is meta data for structured data sets. It gets set by the algorithm during the update information pass.

Set/Get the whole extent of an output port. The whole extent is meta data for structured data sets. It gets set by the algorithm during the update information pass.

int vtkStreamingDemandDrivenPipeline::SetUpdateExtentToWholeExtent ( int port )

If the whole input extent is required to generate the requested output extent, this method can be called to set the input update extent to the whole input extent. This method assumes that the whole extent is known (that UpdateInformation has been called)

If the whole input extent is required to generate the requested output extent, this method can be called to set the input update extent to the whole input extent. This method assumes that the whole extent is known (that UpdateInformation has been called)
