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.

NO_PRIOR_TEMPORAL_ACCESS_CONTINUE

Notifies that the current UPDATE_TIME_STEP() is to be integrated in the output of the current vtkAlgorithm.

NO_PRIOR_TEMPORAL_ACCESS_RESET

Notifies that the filter should reset its internal state.

This bit should be activated if one wants to rerun the time steps from scratch. It does not need to be set on the first update of the pipeline.

Reimplemented in vtkThreadedCompositeDataPipeline.

◆ ProcessRequest()

vtkTypeBool vtkStreamingDemandDrivenPipeline::ProcessRequest	(	vtkInformation *	request,

overridevirtual

Generalized interface for asking the executive to fulfill update requests.

Reimplemented from vtkDemandDrivenPipeline.

◆ Update() [1/3]

virtual

Bring the outputs up-to-date.

◆ Update() [3/3]

virtual vtkTypeBool 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

◆ UpdateTimeDependentInformation()

int vtkStreamingDemandDrivenPipeline::UpdateTimeDependentInformation ( 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.

◆ GetWholeExtent() [1/2]

static void vtkStreamingDemandDrivenPipeline::GetWholeExtent	(	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.

◆ GetWholeExtent() [2/2]

static int * vtkStreamingDemandDrivenPipeline::GetWholeExtent ( 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.

◆ SetRequestExactExtent()

int vtkStreamingDemandDrivenPipeline::SetRequestExactExtent	(	int	port,
		int	flag
	)

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 consumer cannot handle this (i.e. DataSetToDataSetfilter) the image will crop itself. This functionality used to be in ImageToStructuredPoints.

◆ GetRequestExactExtent()

int vtkStreamingDemandDrivenPipeline::GetRequestExactExtent ( 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 consumer cannot handle this (i.e. DataSetToDataSetfilter) the image will crop itself. This functionality used to be in ImageToStructuredPoints.

◆ NO_PRIOR_TEMPORAL_ACCESS()

static vtkInformationIntegerKey * vtkStreamingDemandDrivenPipeline::NO_PRIOR_TEMPORAL_ACCESS ( )

static

Key to tell whether the data has all its time steps generated.

It is typically used for in situ, where you want to be able to visualize a simulation while it is running. It effectively tells the downstream algorithms integrating over all the timesteps that the current set of available timesteps is not necessarily complete. As a result, they will produce a valid output for each requested timestep and keep some cache helping them to retrieve upcoming timesteps as they arrive.

Note: One should check the actual value of this key. Possible values are listed in NO_PRIOR_TEMPORAL_ACCESS_STATES.

◆ GetUpdateExtent() [1/2]

static void vtkStreamingDemandDrivenPipeline::GetUpdateExtent	(	vtkInformation *	,
		int	extent[6]
	)

static

Get/Set the update extent for output ports that use 3D extents.

◆ GetUpdateExtent() [2/2]

static int * vtkStreamingDemandDrivenPipeline::GetUpdateExtent ( vtkInformation * )

static

Get/Set the update extent for output ports that use 3D extents.

◆ GetUpdatePiece()

static int vtkStreamingDemandDrivenPipeline::GetUpdatePiece ( vtkInformation * )

static

Set/Get the update piece, update number of pieces, and update number of ghost levels for an output port.

Similar to update extent in 3D.

◆ GetUpdateNumberOfPieces()

static int vtkStreamingDemandDrivenPipeline::GetUpdateNumberOfPieces ( vtkInformation * )

static

Set/Get the update piece, update number of pieces, and update number of ghost levels for an output port.

Similar to update extent in 3D.

◆ GetUpdateGhostLevel()

static int vtkStreamingDemandDrivenPipeline::GetUpdateGhostLevel ( vtkInformation * )

static

Set/Get the update piece, update number of pieces, and update number of ghost levels for an output port.

Similar to update extent in 3D.
