Requesting testers for Collections enhancements to class Rexx

[Kermit Kiser]

A new experimental version of NetRexx is available for testing: This
version includes support for using Rexx class objects as part of the
Java Collections framework.

Note that an indexed Rexx object is not directly a Collection but rather
a "Map" of keys to values which encompasses a set of keys (keySet), a
collection of values, and a set of key==>value mappings (entrySet). The
updated Rexx objects implement Java interfaces "Map", "Comparable", and
"Iterable" which allow them to be members of "collections" and to also
contain "collections" themselves.

This experimental implementation is non-trivial - it includes 7 new
classes and over 50 new methods, so I would be very surprised if there
are not lots of bugs to squash. In particular, the hashcode functions
have not been addressed yet. After this implementation is debugged and
regression tested, it may become part of a future NetRexx release.

The updated binaries and source code can be found in the NetRexx Plus
project download area on Kenai:

PS: Here is a sample program created to test some of the new features:

say " Testing new collections interfaces in class Rexx  "

/* create a small indexed variable:            */

rc['x']="one"

loop ix over rc
     say "ix=" ix "value="rc[ix]
     end
say "rc.size="rc.size

say " verify base iterator works (including remove method):        "
it=rc.iterator
loop while it.hasNext
     nxt=Rexx it.next
     say "next="nxt
     if nxt="y" then it.remove
     end

say "key x?" rc.containsKey(x)            --        this one works fine
say "val one?" rc.containsValue(Rexx("one"))
say "val one?" rc.containsValue("one")
say "empty?" rc.isEmpty
say rc.get(Rexx("x"))
say rc.get(String "x")
say rc.get("xy")

say " verify values collection and iterator work:        "

Hello Kermit,

    as I'm (unfortunately) still using a  *LOT* of Stem's in my private
code,
due to historic reasons (port from CMS Compiled Rexx), this mail is to
confirm that I'll now download your new version and test it in the next
days.

    When I'm finding problems, how shall I proceed, please?

(a) enter an Issue in KENAI? When yes, under which category?

   *or*

(b) send you a private mail?

Anyway, many thanks for your continuous excellent work on the NetRexx
Compiler!

Thomas Schneider.

Thomas -

This code is experimental and not yet part of the official NetRexx so
don't enter problem reports for it on Kenai. Just send them to me or put
them on the list.

Kermit, OK!
   (drop my other mail just sent to you!)

I will now start to parallel-Test NetRexx3.01RC2 and your after3.01 version,
and send a report to you when I do encounter any problems (with the
examples failing, when dfailing at all)

Kepp up the good work, Kermit!

Thanks in advance,
Thomas.
