Examples of org.conserve.PersistenceManager.refresh()

org.conserve.PersistenceManager.refresh()

Force a refresh of the object from the database, ignoring the cached values for the object. All objects that make up this object are also refreshed, which will affect all objects that share referenced objects with this object. The new object is returned. If the corresponding object has been deleted from the database, null is returned. If the argument is not managed by Conserve, the method will throw an IllegalArumentException. This is a convenience method for {@link #refresh(ConnectionWrapper,Object)}, a ConnectionWrapper will be automatically obtained and released. @param obj the object to refresh. @throws IllegalArumentException if obj is not known by this instance of Conserve. @return the refreshed object or null if the object has been deleted fromthe database. @throws SQLException

    // alter the original object
    so.setName("altered");
    // save the altered object
    persistOne.saveObject(so);
    // update the copy
    SimpleObject copy2 = persistTwo.refresh(copy);
    // make sure the change has propagated
    assertEquals(so.getName(), copy.getName());
    assertEquals(copy.getName(), copy2.getName());
    assertEquals(copy, copy2);
  }

    // alter the original object
    layer3.getLayer1().setName("altered");
    // save the altered object
    persistOne.saveObject(layer3);
    // update the copy
    persistTwo.refresh(copy);
    // make sure the change has propagated
    assertEquals(layer3.getLayer1().getName(), copy.getLayer1().getName());
