Detailed Description

Superclass for all pipeline executives in VTK.

vtkExecutive is the superclass for all pipeline executives in VTK. A VTK executive is responsible for controlling one instance of vtkAlgorithm. A pipeline consists of one or more executives that control data flow. Every reader, source, writer, or data processing algorithm in the pipeline is implemented in an instance of vtkAlgorithm.

Member Function Documentation

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

Reimplemented from vtkObject.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

static int vtkExecutive::IsTypeOf ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkObject.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

virtual int vtkExecutive::IsA ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkObject.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

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

Reimplemented from vtkObject.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

void vtkExecutive::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 vtkObject.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkCompositeDataPipeline, vtkDemandDrivenPipeline, and vtkStreamingDemandDrivenPipeline.

vtkAlgorithm* vtkExecutive::GetAlgorithm ( )

Get the algorithm to which this executive has been assigned.

virtual int vtkExecutive::ProcessRequest ( vtkInformation * request,

vtkInformationVector ** inInfo,

vtkInformationVector * outInfo

) [virtual]

Generalized interface for asking the executive to fullfill pipeline requests.
Reimplemented in vtkCompositeDataPipeline, vtkDemandDrivenPipeline, vtkStreamingDemandDrivenPipeline, and vtkImageImportExecutive.

virtual int vtkExecutive::ComputePipelineMTime ( vtkInformation * request,

vtkInformationVector ** inInfoVec,

vtkInformationVector * outInfoVec,

int requestFromOutputPort,

unsigned long * mtime

) [virtual]

A special version of ProcessRequest meant specifically for the pipeline modified time request. This is an optimization since the request is called so often and it travels the full length of the pipeline. We augment the signature with method arguments containing the common information, specifically the output port through which the request was made and the resulting modified time. Note that unlike ProcessRequest the request information object may be NULL for this method. It also does not contain a request identifcation key because the request is known from the method name.
Reimplemented in vtkCompositeDataPipeline, and vtkDemandDrivenPipeline.

virtual int vtkExecutive::Update ( ) [virtual]

Bring the algorithm's outputs up-to-date. Returns 1 for success and 0 for failure.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkDemandDrivenPipeline, and vtkStreamingDemandDrivenPipeline.

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

Bring the algorithm's outputs up-to-date. Returns 1 for success and 0 for failure.
Reimplemented in vtkCachedStreamingDemandDrivenPipeline, vtkDemandDrivenPipeline, and vtkStreamingDemandDrivenPipeline.

int vtkExecutive::GetNumberOfInputPorts ( )

Get the number of input/output ports for the algorithm associated with this executive. Returns 0 if no algorithm is set.

int vtkExecutive::GetNumberOfOutputPorts ( )

Get the number of input/output ports for the algorithm associated with this executive. Returns 0 if no algorithm is set.

vtkInformationVector* vtkExecutive::GetOutputInformation ( )

Get the pipeline information object for all output ports.

vtkDataObject * ,

vtkInformation * info

) [virtual]

Get the executive managing the given input connection.

virtual void vtkExecutive::SetOutputData ( int port,

vtkInformationVector ** inInfoVec

) [virtual]

virtual vtkAlgorithmOutput* vtkExecutive::GetProducerPort ( vtkDataObject * ) [virtual]

Get the output port that produces the given data object.

void vtkExecutive::SetSharedInputInformation ( vtkInformationVector ** inInfoVec )

Set a pointer to an outside instance of input or output information vectors. No references are held to the given vectors, and setting this does not change the executive object modification time. This is a preliminary interface to use in implementing filters with internal pipelines, and may change without notice when a future interface is created.

void vtkExecutive::SetSharedOutputInformation ( vtkInformationVector * outInfoVec )

Get the output port that produces the given data object.
