org.pentaho.reporting.libraries.resourceloader.ResourceKey
The key is an unique identifier for the resource. Most of the time, this may be an URL, but other (especially database based) schemas are possible.
A resource key must provide an 'equals' implementation. ResourceKeys should be implemented as immutable classes, so that they can be safely stored in collections or on external storages (like caches). @author Thomas Morgner
