de.danet.an.util.persistentmaps.JDBCPersistentMap.store()
Stores the map in persistent store. If the set has not been loaded before, all entries with the current map id are deleted from the persistent store first. Only modified (new, changed, deleted) map entries are changed in the peristent store. @throws IOException problems while storing the map

  ByteArrayOutputStream bo = new ByteArrayOutputStream();
  ObjectOutputStream o = new ObjectOutputStream(bo);
  o.writeObject(map);
  o.close();
  map.remove("HSc");
  map.store();
  map.load();
  assertTrue(map.size() == 2); // Two entries stored in DB  
  ByteArrayInputStream bi = new ByteArrayInputStream(bo.toByteArray());
  ObjectInputStream i = new ObjectInputStream(bi);
  map = (JDBCPersistentMap)i.readObject(); // Three object read

  ObjectInputStream i = new ObjectInputStream(bi);
  map = (JDBCPersistentMap)i.readObject(); // Three object read
  assertTrue(map.size() == 3);  
  i.close();
  map.setConnection(con);
  map.store(); // Three objects stored
  map.clear();
  assertTrue(map.size() == 0);
