Method OCL.parse(OCLInput input) in pivot [message #825454]

Hello,

I have been using for some time Eclipse OCL for my research on the conjunct usage of Ecore and OCL, reason for which I have always used the old Ecore binding with generics to build my prototypes; but I've decided it's finally time to migrate the code to using the pivot metamodel. I have been able to decipher some of the differences by looking at the pivot code. There is however one thing I haven't been able to find; how to parse entire .ocl documents. In the old OCL, there was this method taking the OCL document as parameter and then returning the list of constraints:

public List<CT> parse(OCLInput input)

which I can't find now in the OCL pivot plugin. Has this been implemented already? Is there another way to accomplish parsing an entire document?

PD. Just cross-checking, I realized this question was made already Smile

http://www.eclipse.org/forums/index.php/mv/msg/243456/754603/#msg_754603
However there was no answer so I though I'd ask.

Many thanks in advance,

Juan Cadavid

Hi Juan

There was an answer to the earlier message; but to the wrong question.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=374846 raised to provide
some approximation of the old parse() API.

doLoad_OCL in
/org.eclipse.ocl.examples.xtext.tests/src/org/eclipse/ocl/examples/test/xtext/LoadTests.java
or
/org.eclipse.ocl.examples.xtext.completeocl/src/org/eclipse/ocl/examples/xtext/completeocl/validation/CompleteOCLEObjectValidator.java
shows what to do.

Beware that the Pivot code is of examples quality and is certain to
change, at least in package names, before promotion for the Kepler release.

Regards

Ed Willink

Hi Ed,

Thank you so much for your answer! I will keep into account your remarks on the current status on the pivot meta-model.

Cheers,

Juan
