public interface ResourceLoader
A resource loader knows how to get binary rawdata from a location specified by an resource key. A resource key is a wrapper around any kind of data that is suitable to identify a resource location. The resource key can also hold configuration data for the factory. If the storage system is hierarchical, a new resource key can be derived from a given path-string.
