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.

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 vtkDemandDrivenPipeline.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkReaderExecutive, vtkThreadedCompositeDataPipeline, and vtkImageImportExecutive.

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 vtkDemandDrivenPipeline.

Reimplemented in vtkThreadedCompositeDataPipeline, and vtkImageImportExecutive.

◆ ProcessRequest()

vtkTypeBool vtkStreamingDemandDrivenPipeline::ProcessRequest ( vtkInformation request,
vtkInformationVector **  inInfo,
vtkInformationVector outInfo 
)
overridevirtual

Generalized interface for asking the executive to fulfill update requests.

Reimplemented from vtkDemandDrivenPipeline.

Reimplemented in vtkImageImportExecutive.

◆ Update() [1/3]

vtkTypeBool vtkStreamingDemandDrivenPipeline::Update ( )
overridevirtual

Bring the outputs up-to-date.

Reimplemented from vtkDemandDrivenPipeline.

◆ Update() [2/3]

vtkTypeBool vtkStreamingDemandDrivenPipeline::Update ( int  port)
overridevirtual

Bring the outputs up-to-date.

Reimplemented from vtkDemandDrivenPipeline.

◆ UpdateWholeExtent()

virtual vtkTypeBool vtkStreamingDemandDrivenPipeline::UpdateWholeExtent ( )
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.

◆ 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.
