Detailed Description

Superclass for algorithms that produce only vtkAnnotationLayers as output.

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.

vtkAnnotationLayers* vtkAnnotationLayersAlgorithm::GetOutput ( )
inline

Get the output data object for a port on this algorithm.

vtkAnnotationLayers* vtkAnnotationLayersAlgorithm::GetOutput ( int  index)

Get the output data object for a port on this algorithm.

void vtkAnnotationLayersAlgorithm::SetInput ( vtkDataObject obj)
inline

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.
