Usage
vtkPassInputTypeAlgorithm is a convenience class to make
writing algorithms easier. It is also designed to help
transition old algorithms to the new pipeline architecture.
Ther are some assumptions and defaults made by this class
you should be aware of. This class defaults such that your
filter will have one input port and one output port. If that
is not the case simply change it with SetNumberOfInputPorts
etc. See this classes contstructor for the default. This
class also provides a FillInputPortInfo method that by
default says that all inputs will be DataObject. If that
isn't the case then please override this method in your
subclass. This class breaks out the downstream requests into
seperate functions such as RequestDataObject RequestData and
RequestInformation. The default implementation of
RequestDataObject will create an output data of the same
type as the input.
To create an instance of class vtkPassInputTypeAlgorithm,
simply invoke its constructor as follows
obj = vtkPassInputTypeAlgorithm
Methods
The class vtkPassInputTypeAlgorithm has several methods that
can be used. They are listed below. Note that the
documentation is translated automatically from the VTK
sources, and may not be completely intelligible. When in
doubt, consult the VTK website. In the methods listed below,
obj is an instance of the vtkPassInputTypeAlgorithm class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkPassInputTypeAlgorithm = obj.NewInstance ()
* vtkPassInputTypeAlgorithm = obj.SafeDownCast (vtkObject o)
* vtkDataObject = obj.GetOutput () - Get the output data
object for a port on this algorithm.
* vtkDataObject = obj.GetOutput (int ) - Get the output data
object for a port on this algorithm.
* vtkPolyData = obj.GetPolyDataOutput () - Get the output as
vtkPolyData.
* vtkStructuredPoints = obj.GetStructuredPointsOutput () -
Get the output as vtkStructuredPoints.
* vtkImageData = obj.GetImageDataOutput () - Get the output
as vtkStructuredPoints.
* vtkStructuredGrid = obj.GetStructuredGridOutput () - Get
the output as vtkStructuredGrid.
* vtkUnstructuredGrid = obj.GetUnstructuredGridOutput () -
Get the output as vtkUnstructuredGrid.
* vtkRectilinearGrid = obj.GetRectilinearGridOutput () - Get
the output as vtkRectilinearGrid.
* vtkTable = obj.GetTableOutput () - Get the output as
vtkTable.
* vtkGraph = obj.GetGraphOutput () - Get the output as
vtkGraph.
* vtkDataObject = obj.GetInput () - Get the input data
object. This method is not recommended for use, but lots
of old style filters use it.
* obj.SetInput (vtkDataObject ) - Set an input of this
algorithm. You should not override these methods because
they are not the only way to connect a pipeline. Note that
these methods support old-style pipeline connections. When
writing new code you should use the more general
vtkAlgorithm::SetInputConnection(). These methods
transform the input index to the input port index, not an
index of a connection within a single port.
* obj.SetInput (int , vtkDataObject ) - Set an input of this
algorithm. You should not override these methods because
they are not the only way to connect a pipeline. Note that
these methods support old-style pipeline connections. When
writing new code you should use the more general
vtkAlgorithm::SetInputConnection(). These methods
transform the input index to the input port index, not an
index of a connection within a single port.
* obj.AddInput (vtkDataObject ) - Add an input of this
algorithm. Note that these methods support old-style
pipeline connections. When writing new code you should use
the more general vtkAlgorithm::AddInputConnection(). See
SetInput() for details.
* obj.AddInput (int , vtkDataObject ) - Add an input of this
algorithm. Note that these methods support old-style
pipeline connections. When writing new code you should use
the more general vtkAlgorithm::AddInputConnection(). See
SetInput() for details.
