field length

How to find the max string length for a BDM class field?

If I have BDM class "com.company.model.MyBDM" with a string field "field1", declared to have a max size of 80 in the business data definition of the studio, how can I determine this max size in groovy connector scripts (or other script types).

In particular: I'd like to be able to add contract constraints to police the max lengths allowed without having to hard-code the length in the BDM definition and all related scripts, constraints and expressions.

I'm pretty sure it has something to do with annotations, but I cant work out the correct syntax.

Many thanks
