Examples of org.locationtech.udig.catalog.IService.resolve()

org.locationtech.udig.catalog.IService.resolve()
Will attempt to morph into the adaptee, and return that object. Harded coded to capture the IService contract.
That is we *must* resolve the following:
- IService: this
- IServiceInfo.class: getInfo
- ICatalog.class: parent
Recomended adaptations:
- ImageDescriptor.class: for a custom icon
- List.class: members
May Block.
Example implementation:
```
  public <T> T resolve( Class<T> adaptee, IProgressMonitor monitor ) throws IOException { if (monitor == null) monitor = new NullProgressMonitor();  if (adaptee == null) throw new NullPointerException("No adaptor specified" ); if (adaptee.isAssignableFrom(API.class)) { return adaptee.cast(getAPI(monitor)); } return super.resolve(adaptee, monitor); }  
```
@param adaptee @param monitor @return instance of adaptee, or null if unavailable (IServiceInfo and List mustbe supported) @see IServiceInfo @see IGeoResource @see IResolve#resolve(Class,IProgressMonitor)
