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.

static

Key to store the bounding box of a portion of the data set in pipeline information.

static vtkInformationIntegerKey* vtkStreamingDemandDrivenPipeline::EXACT_EXTENT ( )
static

Key to specify the request for exact extent in pipeline information.

static vtkInformationDoubleVectorKey* vtkStreamingDemandDrivenPipeline::TIME_STEPS ( )
static

Key to store available time steps.

static vtkInformationDoubleVectorKey* vtkStreamingDemandDrivenPipeline::TIME_RANGE ( )
static

Key to store available time range for continuous sources.

static vtkInformationDoubleVectorKey* vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS ( )
static

Update time steps requested by the pipeline.

static vtkInformationDoubleKey* vtkStreamingDemandDrivenPipeline::PRIORITY ( )
static

Key that specifies from 0.0 to 1.0 the pipeline computed priority of this update extent. 0.0 means does not contribute and can be skipped.

static vtkInformationDoubleKey* vtkStreamingDemandDrivenPipeline::UPDATE_RESOLUTION ( )
static

Key that specifies a requested resolution level for this update extent. 0.0 is very low and 1.0 is full resolution.

static vtkInformationIntegerKey* vtkStreamingDemandDrivenPipeline::REMOVE_ATTRIBUTE_INFORMATION ( )
static

Used internally to validate meta information as it flows through pipeline

static

The following keys are meant to be used by an algorithm that works with temporal data. Rather than re-executing the pipeline for each timestep, if the reader, as part of its API, contains a faster way to read temporal data, algorithms may use these keys to request temporal data from the reader. See also: vtkExtractArraysOverTime.

Issues pipeline request to determine and return the priority of the piece described by the current update extent. The priority is a number between 0.0 and 1.0 with 0 meaning skippable (REQUEST_DATA not needed) and 1.0 meaning important.

Called before RequestUpdateExtent() pass on the algorithm. Here we remove all update-related keys from the input information. Currently this only removes the fast-path related keys.
