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.

◆ Update() [3/3]

virtual int vtkStreamingDemandDrivenPipeline::Update	(	int	port,
		vtkInformationVector *	requests
	)

virtual

This method enables the passing of data requests to the algorithm to be used during execution (in addition to bringing a particular port up-to-date).

The requests argument should contain an information object for each port that requests need to be passed. For each of those, the pipeline will copy all keys to the output information before execution. This is equivalent to:

* executive->UpdateInformation();
* for (int i=0; i<executive->GetNumberOfOutputPorts(); i++)
* {
* vtkInformation* portRequests = requests->GetInformationObject(i);
* if (portRequests)
* {
* executive->GetOutputInformation(i)->Append(portRequests);
* }
* }
* executive->Update();
*

Available requests include UPDATE_PIECE_NUMBER(), UPDATE_NUMBER_OF_PIECES() UPDATE_EXTENT() etc etc.

◆ PropagateUpdateExtent()

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.

◆ PropagateTime()

int vtkStreamingDemandDrivenPipeline::PropagateTime ( int outputPort )

Propagate time through the pipeline.

this is a special pass only necessary if there is temporal meta data that must be updated

◆ SetWholeExtent()

static int vtkStreamingDemandDrivenPipeline::SetWholeExtent	(	vtkInformation *	,
		int	extent[6]

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.

◆ SetRequestExactExtent()

int vtkStreamingDemandDrivenPipeline::SetRequestExactExtent	(	int	port,

	)

This request flag indicates whether the requester can handle more data than requested for the given port.

Right now it is used in vtkImageData. Image filters can return more data than requested. The the consumer cannot handle this (i.e. DataSetToDataSetFitler) the image will crop itself. This functionality used to be in ImageToStructuredPoints.

◆ GetRequestExactExtent()

int vtkStreamingDemandDrivenPipeline::GetRequestExactExtent ( int port )

◆ SetUpdateExtentToWholeExtent() [1/2]

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)
