There are a few readers in VTK/IO that are derived from a
vtkMultiBlockDataSetAlgorithm that might be useful for reference:

  vtkFLUENTReader.h
  vtkGenericEnSightReader.h
  vtkMultiBlockPLOT3DReader.h
  vtkOpenFOAMReader.h

The multi-block-dataset can hold various data types.

If you wish to have multiple output ports (say a different port for each
data type), the only example I saw in VTK/IO is this one: 
  vtkGaussianCubeReader


I unfortunately don't know how multi-port output gets connected with the
rest of the pipeline.
