 * Some post processors implement a consolidated event stream.
 * That is, they have an internal event stream that contains data obtained by processing the underlying event streams.
 * Typical examples are the binning event streams like Mean, RMS etc.
 * In this case the retrieval servlet, sends the consolidated event stream instead of the underlying streams.
