Class DbStringSet

java.lang.Object
  net.sourceforge.pain.db.DbCollection
      net.sourceforge.pain.db.DbAbstractStringMap
          net.sourceforge.pain.db.DbStringSet

All Implemented Interfaces:

java.util.Collection, java.util.Set

public final class DbStringSet

extends net.sourceforge.pain.db.DbAbstractStringMap

implements java.util.Set

This class implements the Set interface. Only not null String values supported.
PAiN Db will not support more general serializable objects Set as it brokes database design
but Strings(Immutable) Sets are too convinient to be missed. This class is still experimental and could be removed with next release. (possible usage alternative: Cookie class and StingKeyMap)
