SignalSystemManager (JMRI API)

All Superinterfaces:

Manager<SignalSystem>, PropertyChangeProvider, SilenceablePropertyChangeProvider, VetoableChangeProvider

All Known Implementing Classes:

DefaultSignalSystemManager
```
public interface SignalSystemManager
extends Manager<SignalSystem>
```
Interface for obtaining information about signal systems.
Each NamedBean here represents a single signal system. The actual objects are SignalAspectTable objects; that's a current anachronism, soon to be fixed.
See the common implementation for information on how loaded, etc.
