Copying non-key fields (like clone)

I need to be able to duplicate a record, assign it new key values using 
the generator, then modify a few of the other (non-key) fields.

I'm updating to version 3.0.  In version 2.x I had added a method in 
meta called meta.isKeyField(), which allowed me to determine whether a 
field was just a normal database field.  This allowed me to write a 
method like this in one of my classes:

    public void copyAllNonRefFields(ParcelORM source) {
        for (int i=0;i<fieldValues.length;i++) {
            if (!meta.isKeyField(i)) {
                fieldValues[i]= source.fieldValues[i];
            }
        }
        setDirty();
    }

This worked for me. 

What's the best way to do something similar in Version 3?  Basically I 
want to be able to clone() a record in the database, but obviously the 
clone should have a new key generated.  I see 
SRecordInstance.fieldValues now has package visibility, suggesting that 
direct access to it from subclasses (like in my code snippet above) is 
no longer a good idea.

Thanks in advance,

(PS coming back to SimpleORM after a bad experience with Hibernate.)
