Class LocationMapper

java.lang.Object
  org.apache.jena.riot.stream.LocationMapper

public class LocationMapper
extends Object

Alternative locations for URIs. Maintains two maps: single item alternatives and alternative prefixes. To suggest an alternative location, first check the single items, then check the prefixes. A LocationMapper can be configured by an RDF file. The default for this is "etc/location-mapping.n3". There is a default LocationMapper which is used by the global @link{FileManager}.
