NullSite

java.lang.Object
- diva.canvas.AbstractSite
- - diva.canvas.connector.NullSite

All Implemented Interfaces:

Site

public class NullSite
extends AbstractSite
```
A site that doesn't do anything useful. Sometimes this is needed as a placeholder for objects that expect sites, but because other objects they depend on haven't been created yet, can't have them.
