| [gmf-dev] [EMFT - API Change] Bugzilla 125684: Support creation of query |
| Description: | The IOCLHelper and ExpressionsUtil
types have new createQuery() methods mirroring the existing createInvariant()
methods, to clarify the distinction between query expressions and constraint
expressions. Previously, non-boolean-valued query expressions could
only be created by calling the createInvariant() methods, which doesn't
make sense. Moreover, createInvariant() did not check that the _expression_
is of boolean type because it was meant to be used for queries.
Both of these problems are fixed by this bugzilla, but it means an API change in the existing IOCLHelper.createInvariant() and ExpressionsUtil.createInvariant() methods. They now throw OCLParsingExceptions on non-boolean expressions. |
| New API Availability: | Next OCL build. |
| Old API Removal: | No API removed; the precondition contract is changed. |
| Tracking: | Bug 125684 |
| Clients Migrated: | EMFT (OCL examples, Query, Validation) |
| Other Clients' Actions: | Replace usage of IOCLHelper.createInvariant()
with IOCLHelper.createQuery() wherever the _expression_ string is not required
to be boolean-valued.
Likewise for ExpressionsUtil.createInvariant(). |
