Class DatabaseRetrievedObject

java.lang.Object
  net.sourceforge.toscanaj.model.database.DatabaseRetrievedObject

All Implemented Interfaces:

FCAElement

public class DatabaseRetrievedObject

extends java.lang.Object

implements FCAElement

To do:

drop distinctions between objects with or without keys and with or without special clauses. The object should have only one clause attached which gives whatever this object represents, the clause for the full object set of a label should not be part of instances of this class. Probably it is a good idea if aggregates just return null as their clause -- they just don't have any clause specific for them. This change needs first dropping the distinction between different viewers in the DatabaseViewerManager.
