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

org.locationtech.udig.catalog.IGeoResource.resolve()
Blocking operation to resolve into the adaptee, if available.
Required adaptions:
- GeoResource.class - this
- IGeoResourceInfo.class - getInfo( monitor ) ie about this handles contents
- IService.class - service( monitor ) ie that is responsible for this GeoResource
Example Use (no casting required!):
```
  IGeoResourceInfo info = resolve(IGeoResourceInfo.class);  
```
Recommended adaptions:
- ImageDescriptor.class (for icon provided by external service)
- List.class - members( monitor ) ie children of this georesource as in the wms layer case
@param adaptee @param monitor @return instance of adaptee, or null if unavailable (IGeoResourceInfo and IService must besupported) @see IGeoResourceInfo @see IService @see IResolve#resolve(Class,IProgressMonitor)
