Hi,
I'd like to contribute a little static method "Util.assume" that I used a lot at metas. It's similar to the java "assert" keyword, but there are two advantages:

1. If the assumption doesn't hold, it throws and AdempiereException, which adempiere itself can handle (display to user, create AD_Issue etc) much better than the AssertionError that would be thrown by assert.
2. Assumptions are always checked, not only when the "-ea" cmd-line parameter is used. I think that this is more suitable for an ERP system, because of the bigger complexity it comes with.
Plus, for me it turned you that I never had to access the DB to check my assumptions. Therefore, the performance impact turned out to be neglectable.

WDYT?

Best regards
Tobi

    Hi Tobi!

    have you some code lines as example?

    so we can see how would be used.

    kind regards
    Victor
