Section: Visualization Toolkit Filtering Classes
* REQUEST_INFORMATION: The producers have to provide information about the contents of the composite dataset in this pass. Sources that can produce more than one piece (note that a piece is different than a block; each piece consistes of 0 or more blocks) should set MAXIMUM_NUMBER_OF_PIECES to -1.
* REQUEST_UPDATE_EXTENT: This pass is identical to the one implemented in vtkStreamingDemandDrivenPipeline
* REQUEST_DATA: This is where the algorithms execute. If the vtkCompositeDataPipeline is assigned to a simple filter, it will invoke the vtkStreamingDemandDrivenPipeline passes in a loop, passing a different block each time and will collect the results in a composite dataset. .SECTION See also vtkCompositeDataSet
To create an instance of class vtkCompositeDataPipeline, simply invoke its constructor as follows
obj = vtkCompositeDataPipeline
obj
is an instance of the vtkCompositeDataPipeline class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkCompositeDataPipeline = obj.NewInstance ()
vtkCompositeDataPipeline = obj.SafeDownCast (vtkObject o)
vtkDataObject = obj.GetCompositeOutputData (int port)
- Returns the data object stored with the DATA_OBJECT() in the
output port
