When I write an OCL-query and try to check for a specific UML type I
write "oclIsTypeOf(uml2::kernel::Component)" or at least
"oclIsTypeOf(...::something)". Can someone describe the pathes of the
UML2 meta model used in the OCL plug-in. I've tried it with
"org::eclipse::uml2::Component" and "uml2::kernel::Component", both
giving a SemanticException: ERROR in (operationArgs): (Unrecognizable type).
Kind regards,
Daniel

Hello Christian,
it's even simpler and after debugging I've found the point where the
type in the OCL expression is resolved. It seems that
oclIsTypeOf(Component) works.
If I prepend a package prefix, e.g. uml::Component, it tries to find the
uml package in the sub packages of the default package which is already
the UML2Package.
Kind regards,
Daniel

Hi, Daniel,
The path that you need is simply "uml::Component" as an example. The path
reflects the Ecore naming structure, not the Java names. The UML2's
EPackage nsPrefix is "uml". I think that the namespace prefix of packages
is used instead of the names because it is what generally appears in XMI as
a dot-separated path (e.g., ocl.expr.OperationCallExp in the OCL metamodel,
where packages are nested).
Cheers,
Christian
