// .NAME vtkCompositeDataSetAlgorithm - Superclass for algorithms that produce only vtkCompositeDataSet as output
// .SECTION Description
// Algorithms that take any type of data object (including composite dataset)
// and produce a vtkCompositeDataSet in the output can subclass from this
// class.

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

// Description:
// 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.
