 Usage

vtkAnnotationLayersAlgorithm is a convenience class to make
writing algorithms easier. It is also designed to help
transition old algorithms to the new pipeline architecture.
There 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 class constructor for the default. This class
also provides a FillInputPortInfo method that by default
says that all inputs will be vtkAnnotationLayers. If that
isn't the case then please override this method in your
subclass. This class breaks out the downstream requests into
separate functions such as ExecuteData and
ExecuteInformation. For new algorithms you should implement
RequestData( request, inputVec, outputVec) but for older
filters there is a default implementation that calls the old
ExecuteData(output) signature. For even older filters that
don't implement ExecuteData the default implementation calls
the even older Execute() signature.
To create an instance of class vtkAnnotationLayersAlgorithm,
simply invoke its constructor as follows

    obj = vtkAnnotationLayersAlgorithm



 Methods

The class vtkAnnotationLayersAlgorithm 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 vtkAnnotationLayersAlgorithm
class.

* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkAnnotationLayersAlgorithm = obj.NewInstance ()
* vtkAnnotationLayersAlgorithm = obj.SafeDownCast (vtkObject
  o)
* vtkAnnotationLayers = obj.GetOutput () - Get the output
  data object for a port on this algorithm.
* vtkAnnotationLayers = obj.GetOutput (int index) - Get the
  output data object for a port on this algorithm.
* obj.SetInput (vtkDataObject obj) - 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 index, vtkDataObject obj) - 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.
