Filters in DDD Repository

Question

There is Campaign Entity and for that, I have CampaignRepository which have this functions

1. public IList FindAll();
2. public Campaign FindByCampaignNumber(st

Answer 1

You should be able to do all of the above with the following repository method:

List findCampaigns(Date fromCreationDate, Date toCreationDate, int offset, Integer limit) {

   if (fromCreationDate != null) add criteria...
   if (toCreationDate != null) add criteria...
   if (limit != null) add limit...
}

This is how I do it and it works very well.
