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

org.locationtech.udig.catalog.IGeoResource.canResolve()

Harded coded to capture the IGeoResource contract.

That is we *must* resolve the following:

Required adaptions:

GeoResource.class - this
IGeoResourceInfo.class - getInfo (ie about this handles contents)
IService.class - service (ie that is responsible for this GeoResource)

Recommendated adaptions:

ImageDescriptor.class (for icon provided by external service)
List.class - members (ie children of this georesource as in the wms layer case)

Here is an implementation example (for something that can adapt to ImageDescriptor and FeatureSource):

  public <T> boolean canResolve( Class<T> adaptee ) { return adaptee != null && (adaptee.isAssignableFrom(ImageDescriptor.class) || adaptee.isAssignableFrom(FeatureSource.class) || super.canResolve(adaptee)); }

            Point bottomRight = currentContext.worldToPixel(new Coordinate(renderREnv.getMaxX(), renderREnv.getMaxY()));
            Rectangle screenSize = new Rectangle(upperLeft);
            screenSize.add(bottomRight);


            final IGeoResource resource = getContext().getGeoResource();
            if (resource == null || !resource.canResolve(JGTtmsGeoResource.class)) {
                getContext().setStatus(ILayer.DONE);
                return;
            }
            JGTtmsGeoResource jgtTmsGeoResource = resource.resolve(JGTtmsGeoResource.class, monitor);
            JGTtmsProperties tmsProperties = jgtTmsGeoResource.getTmsProperties();
