Hi there,
I'm new to this EMFT group so I have a question that might be kind of
stupid but... Is it possible to use the OCL library programmatically in
out-of-the-box applications (stand alone applications from outside
Eclipse)? I'm also using uml2 EMF project in order to "browse" and
create UML diagrams. Some of these diagrams might have some OCL
constraints and I need to parse them. Any idea if this is possible and
if there are any examples for it?
Thanks very, very much in advance for your time...
All the best

Hello, Luis,
The EMFT OCL parser can be used stand-alone, but you will have to fiddle the
JARs a bit (we have a bug asking to support a stand-alone build in the next
release, as EMF does). You need to extract the lpgjavaruntime.jar file
from the org.eclipse.emf.ocl_1.0.1.v2006etc.jar file and include it on your
classpath.
Out-of-the-box, EMFT OCL will parse and evaluate constraints and queries on
Ecore models. That is to say, its metamodel is Ecore (more like
EssentialOCL), not UML (which would be more like CompleteOCL). If you want
to parse OCL constraints in UML models, then you will have some work to do
to create a UML Environment (see previous discussion on this topic in this
newsgroup). The MDT project's UML component has an open bug for OCL
support in UML.
To get started with EMFT OCL on Ecore models, install the OCL Interpreter
example into your workspace (File -> New -> Example... menu) and follow the
tutorial in the on-line help.
HTH,
Christian

Hi Christian,
Thanks very much for your answer. For the moment I really just need to
parse OCL constraints. For now I don't need to perform queries since I'm
just performing a transformation of OCL into another language. So it
would help if there are any examples (even if they are very small) that
show how to use the EMFT COL parser in order to get the structure of an
OCL constraint. Is there any OCL Ecore based meta-model that can also be
used?
Thanks again,
LP

Hi, Luis,
The org.eclipse.emf.ocl plug-in defines an Ecore model of the OCL language:
OCL.ecore. The API is defined by the following packages:
- org.eclipse.emf.ocl.expressions
- org.eclipse.emf.ocl.types
- org.eclipse.emf.ocl.uml
- org.eclipse.emf.ocl.utilities
- org.eclipse.emf.ocl.query
For an example of how to parse an OCL expression (constructing an instance
of the OCLExpression type from the OCL metamodel), install the OCL
Interpreter example that I referred to, below. Then see the
org.eclipse.emf.ocl.examples.interpreter.console.OCLResource class's save()
method to see how to use an IOCLHelper to parse an expression (never mind
the fancy anonymous subclass of EcoreEnvironmentFactory).
The IOCLHelper interface provides all of the API you need to generate an
OCLExpression from OCL text.

Christian
