Hi,
After some experiments, I have found that the toString() operation is
not defined for Real types in ATL, thus contradicting the statement in
the ATL User Manual
( http://www.eclipse.org/m2m/atl/doc/ATL_User_Manual%5Bv0.7%5D .pdf),
4.1.4.3: "The toString() operation, available for both the integer and
*real* data types returns a string representing the integer/real value"
I'm attaching a very simple example that can be use to reproduce the
issue, composed of a metamodel with a class using a Real attribute
(Dummy.ecore), a model conforming to it (dummy-sample.ecore) and a very
simple query ATL that just print the attributes (DummyQuery.atl).
When I execute the query I get:
INFO: attReal=OclUndefined
attInteger=12
attString=foo
but I expected to get:
INFO: attReal=3.14
attInteger=12
attString=foo
So, I'm doing something wrong (my experience with ATL is not too long :)
or actually is there a issue with toString() on Real type? In the later
case, is there any workaround, please?
Thanks!
Best regards,
------
