Class OBlockManager

java.lang.Object
  jmri.managers.AbstractManager
      jmri.jmrit.logix.OBlockManager

All Implemented Interfaces:

PropertyChangeListener, EventListener, Manager

public class OBlockManager
extends AbstractManager
implements PropertyChangeListener

Basic Implementation of a OBlockManager.

Note that this does not enforce any particular system naming convention.

Note this is a concrete class, there are now 2 types of Blocks (LayoutBlocks use a Block member. LBlocks use inheritance. Perhaps now the proxyManager strategy of interface/implementation pairs like other Managers should be implemented.
