Re: Copying non-key fields (like clone)

Welcome back.  

Is SFieldScalar.isPrimaryKey what you want?  

(SimpleORM 3.0 is more focused on columns than references, which simplifies it.)

In general, all variables should have package scope.  Then you can write your own class and put it in the simpleorm package and poke at them.  But only in emergencies!

If you end up producing a number of useful methods like clone, then put them in a package like SRecordUtil and we will incorporate them into the source.  But be sure to include a test case.

Anthony
