How does "constraints" feature work?

[Manoel Campos]

I'm wondering how the constraint feature of classes and fields works.

The documentation only explains briefly how to add constraints but doesn't explain how it works.

I thought that this feature would be used to defined required, min, max, unique constraints, 

but I don't know exactly how to code these characteristics, because the only available

field where I could inform my constraint is the specification field (that is a text field).

I think that It would have combo boxes where I can choose the constraint type (required, max, min, etc)

and specific fields would appear to allow us defining the constraint.

Hi,

Constraint in StarUML is no more than a just textual annotation. It doesn't support any executable language like OCL (Object Constraint Language). Just enter your-own expression in "specification" field of the Constraint.

Thanks,
