                                 javax.persistence.criteria.Path datesPath,
                                 String startDateFieldName,

• The "activeStart" effective date has be prior or equal to today
• For the record to remain active, the "activeEnd" date can be either left unspecified, or be after today

Parameters:

datesPath - the Path expression that can be used to retrieve the date fields

startDateFieldName - the name of the start date field, for example, "activeStartDate"

endDateFieldName - the name of the end date field, for example, "activeEndDate"

notArchived

public static void notArchived(javax.persistence.criteria.CriteriaBuilder builder,
                               List<javax.persistence.criteria.Predicate> restrictions,
                               javax.persistence.criteria.Path archivedPath,
                               String archivedFieldName)

given a list of AND-ed restrictions, it determines wether or not the record is "archived", and adds the necessary restrictions. A record is considered "archived" when the ARCHIVED field is explicitly "Y", so both null and "N" will do as non-archived
