evaluateRecord

public Object evaluateRecord(OIdentifiable iRecord,
                             ODocument iCurrentResult,
                             OSQLFilterCondition iCondition,
                             Object iLeft,
                             Object iRight,
                             OCommandContext iContext)

At run-time the evaluation per record must return always true since the recordset are filtered at the beginning unless an operator can work in both modes. In this case sub-class must extend it.
