Class Prefixes

java.lang.Object
  org.apache.any23.rdf.Prefixes

public class Prefixes
extends Object

A mapping from prefixes to namespace URIs. Supports "volatile mappings", which will be overwritten without notice when mappings are merged, while for normal mappings this causes an exception. This allows combining "hard" mappings (which must be retained or something breaks) and "soft" mappings (which might be read from input RDF files and should be retained only if they are not in conflict with the hard ones).
