Description Henrik Lindberg

2010-10-20 22:26:13 EDT

An anticipated common user error is to enter the same constant case expression multiple times (either for the same case (harmless), or for different cases (not good).

The constant evaluator can be used to also catch all expression cases. 
Examples:

case 10 : ...
case 5+5 : ...
case 10 : ...

Cases #2 and #3 are unreachable.

The other unreachable cases are validated in the EMF model. But this validation requires access to evaluator - add the validation in the BeeLangJavaValidator.
