RE: [mdt-ocl.dev] When use Operations and Def?
|
Hi Andreza,
First, I would ask you to raise such questions in the OCL
newsgroup (now known as forum).
To answer your question, operations declared in the metamodels
are the actual operations that the metaclasses have. You can use them in
any OCL scripts/environments - they are always available since they belong to
the metaclasses.
Operations declared with "def" are defined on a metaclass
context but do not actually belong to the metaclass. Inside your
OCL environment you can use them the same way you use operations declared
in metaclasses. However, they are not available outside your
environment, i.e. in other OCL scripts. You can think of "def"-operations as of
some additional queries which you can use for the purposes of your
script.
Regards,
- Alex.
Hello everybody,
I have seen several metamodels and I have noted
that some of them declare operations in its metaclasses (with the attributes)
and some of them declare operations using "def".
I want to know the
difference for defining operations using "def" and declaring operations in the
metaclass.
Thanks.
