Hello,
is it possible to add variable-value-pairs to a query before it is parsed?
The idea is that I want to use other bound variables than 'self' in my
OCL expression. I want to reference existing objects directly. In OCL
this would have been solved by a let-expression. I don't want to use the
let-expression and OCL do the binding but I want to directly assign it
(maybe by some environment?).
Is this possible and if it is, how do I achieve this?
Cheers,
Alexander Dotor

Hi, Alexander,
Yes, you can inject variables into your OCL parsing and evaluation
environment. Have a look at the
OCL Developer Guide
Programmer's Guide
Advanced Topics
Customizing the Environment
topic in the SDK documentation (Eclipse Help viewer). The first heading
"Defining Global Variables" is what you need.
HTH,
Christian
