Examples of org.locationtech.udig.catalog.ServiceParameterPersister

org.locationtech.udig.catalog.ServiceParameterPersister
Allows IService connection parameters to be stored into a preference object - and for restoring Service again.
IResolves that are not services will be ignored; the default implementation of locateService( URL, Map ) will add the created services into the provided catalog.
{@link #locateService(URL,Map)} can be overridden to not create andadd the service to the catalog.
