Member Function Documentation

static vtkDemandDrivenPipeline* vtkDemandDrivenPipeline::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkStreamingDemandDrivenPipeline, vtkThreadedStreamingPipeline, and vtkImageImportExecutive.

virtual const char* vtkDemandDrivenPipeline::GetClassName (  )  [virtual]

static int vtkDemandDrivenPipeline::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type 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 vtkExecutive.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkStreamingDemandDrivenPipeline, vtkThreadedStreamingPipeline, and vtkImageImportExecutive.

virtual int vtkDemandDrivenPipeline::IsA ( const char *  name  )  [virtual]

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 vtkExecutive.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkStreamingDemandDrivenPipeline, vtkThreadedStreamingPipeline, and vtkImageImportExecutive.

static vtkDemandDrivenPipeline* vtkDemandDrivenPipeline::SafeDownCast ( vtkObject o  )  [static]

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 vtkExecutive.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkStreamingDemandDrivenPipeline, and vtkThreadedStreamingPipeline.

virtual int vtkDemandDrivenPipeline::ProcessRequest ( vtkInformation request,
vtkInformationVector **  inInfo,
vtkInformationVector outInfo 
) [virtual]

Generalized interface for asking the executive to fullfill update requests.

Reimplemented from vtkExecutive.

Reimplemented in vtkCompositeDataPipeline, vtkStreamingDemandDrivenPipeline, vtkThreadedStreamingPipeline, and vtkImageImportExecutive.

virtual int vtkDemandDrivenPipeline::ComputePipelineMTime ( vtkInformation request,
vtkInformationVector **  inInfoVec,
vtkInformationVector outInfoVec,
int  requestFromOutputPort,
unsigned long *  mtime 
) [virtual]

Implement the pipeline modified time request.

Reimplemented from vtkExecutive.

virtual int vtkDemandDrivenPipeline::Update (  )  [virtual]

Bring the algorithm's outputs up-to-date. Returns 1 for success and 0 for failure.

Reimplemented from vtkExecutive.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, and vtkStreamingDemandDrivenPipeline.

virtual int vtkDemandDrivenPipeline::Update ( int  port  )  [virtual]

Bring the algorithm's outputs up-to-date. Returns 1 for success and 0 for failure.

Reimplemented from vtkExecutive.

Reimplemented in vtkCachedStreamingDemandDrivenPipeline, and vtkStreamingDemandDrivenPipeline.

virtual unsigned long vtkDemandDrivenPipeline::GetPipelineMTime (  )  [virtual]

Get the PipelineMTime for this exective.

virtual int vtkDemandDrivenPipeline::SetReleaseDataFlag ( int  port,
int  n 
) [virtual]

Set whether the given output port releases data when it is consumed. Returns 1 if the the value changes and 0 otherwise.

virtual int vtkDemandDrivenPipeline::GetReleaseDataFlag ( int  port  )  [virtual]

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]

Bring the output data object's existence up to date. This does not actually produce data, but does create the data object that will store data produced during the UpdateData step.

Implements vtkExecutive.

virtual int vtkDemandDrivenPipeline::UpdateInformation (  )  [virtual]

Bring the output information up to date.

virtual int vtkDemandDrivenPipeline::UpdateData ( int  outputPort  )  [virtual]

Bring the output data up to date. This should be called only when information is up to date. Use the Update method if it is not known that the information is up to date.

static vtkInformationRequestKey* vtkDemandDrivenPipeline::REQUEST_DATA_OBJECT (  )  [static]

Key defining a request to make sure the output data objects exist.

static vtkInformationRequestKey* vtkDemandDrivenPipeline::REQUEST_INFORMATION (  )  [static]

Key defining a request to make sure the output information is up to date.

static vtkInformationRequestKey* vtkDemandDrivenPipeline::REQUEST_DATA (  )  [static]

Key defining a request to make sure the output data are up to date.

static vtkInformationRequestKey* vtkDemandDrivenPipeline::REQUEST_DATA_NOT_GENERATED (  )  [static]

Key defining a request to mark outputs that will NOT be generated during a REQUEST_DATA.

static vtkInformationIntegerKey* vtkDemandDrivenPipeline::RELEASE_DATA (  )  [static]

Key to specify in pipeline information the request that data be released after it is used.

static vtkInformationIntegerKey* vtkDemandDrivenPipeline::DATA_NOT_GENERATED (  )  [static]

Key to store a mark for an output that will not be generated. Algorithms use this to tell the executive that they will not generate certain outputs for a REQUEST_DATA.

static vtkDataObject* vtkDemandDrivenPipeline::NewDataObject ( const char *  type  )  [static]

Create (New) and return a data object of the given type. This is here for backwards compatibility. Use vtkDataObjectTypes::NewDataObject() instead.

static vtkInformationIntegerKey* vtkDemandDrivenPipeline::REQUEST_REGENERATE_INFORMATION (  )  [static]

Key to be used for REQUEST_INFORMATION and REQUEST_DATA_OBJECT passes when you modification time should not be taken into account.
