Detailed Description

Superclass of all classes generating data tree nodes (instances of class mitk::DataNode) as output.

In itk and vtk the generated result of a ProcessObject is only guaranteed to be up-to-date, when Update() of the ProcessObject or the generated DataObject is called immediately before access of the data stored in the DataObject. This is also true for subclasses of mitk::BaseProcess and thus for mitk::DataNodeSource.

Returns the n'th output of the base data source

Parameters:

idx	the index of the wanted output

Returns:

the output with index idx.
