Usage
vtkPointSetAlgorithm 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 PointSet. 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
ExecuteInformation. The default implementation of
RequestDataObject will create an output data of the same
type as the input.
To create an instance of class vtkPointSetAlgorithm, simply
invoke its constructor as follows
obj = vtkPointSetAlgorithm
Methods
The class vtkPointSetAlgorithm 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 vtkPointSetAlgorithm class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkPointSetAlgorithm = obj.NewInstance ()
* vtkPointSetAlgorithm = obj.SafeDownCast (vtkObject o)
* vtkPointSet = obj.GetOutput () - Get the output data
object for a port on this algorithm.
* vtkPointSet = obj.GetOutput (int ) - Get the output data
object for a port on this algorithm.
* vtkPolyData = obj.GetPolyDataOutput () - Get the output as
vtkPolyData.
* vtkStructuredGrid = obj.GetStructuredGridOutput () - Get
the output as vtkStructuredGrid.
* vtkUnstructuredGrid = obj.GetUnstructuredGridOutput () -
Get the output as vtkUnstructuredGrid.
* 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.SetInput (vtkPointSet ) - 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 , vtkPointSet ) - 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 (vtkPointSet ) - 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 , vtkPointSet ) - 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.
* vtkDataObject = obj.GetInput ()
