the actual execution happens, the type of data returned by the iterator must be given
explicitly in the form of the type information. This method is useful for cases where the type
is generic. In that case, the type class (as given in {@link #fromCollection(Iterator, Class)}
does not supply all type information.

a parallelism of one.
