Marshall Schor commented on UIMA-1524:
--------------------------------------
You are correct - these are not solely stream operations. THe object produced
by the select() call would not be a stream object, but a special object that
would implement the additional methods described in the wiki link above. At
the first "stream" operation, it would make a suitable stream, based on all the
information collected from the builders up to that point, and from then on, it
would be a stream.
I would add the "select(...) method to the cas/jcas, the FSArray and FSList
objects. So these should work across all of them.
Example of use: selectFollowing(type, fs, n)
{code}
cas.select(type).startAt(fs).limit(n) ...
// the limit(n) is a stream call, and would convert the select-produced object
to a stream at that point.
{code}
> JFSIndexRepository should be enhanced with new generic methods
