    • findLongestPrefix

      public static Map.Entry<String,String> findLongestPrefix(org.apache.jena.shared.PrefixMapping pm, String uri)
      Finds the longest prefix. Performance depends on the provided prefix mapping type: Lookups on PrefixMapping2 are recursively delegated to the inner local/global prefix mappings. Lookups on PrefixMappingTrie are optimized - otherwise all entries will be scanned.
      Parameters:
      pm -
      uri -
      Returns:

    • findLongestPrefixCore

      public static Map.Entry<String,String> findLongestPrefixCore(org.apache.jena.shared.PrefixMapping pm, String uri)
      Linear scan of all prefix mappings to find the longest prefix. null if none found.
      Parameters:
      pm -
      uri -
      Returns:

    • usedPrefixes

      public static org.apache.jena.shared.PrefixMapping usedPrefixes(org.apache.jena.shared.PrefixMapping pm, Set<org.apache.jena.graph.Node> nodes)

    • toString

      public static String toString(org.apache.jena.shared.PrefixMapping prefixMapping, org.apache.jena.riot.RDFFormat rdfFormat)
      Convert a prefix mapping to a string

    • fromString

      public static org.apache.jena.shared.PrefixMapping fromString(String str, org.apache.jena.riot.Lang lang)

    • readPrefixes

      public static org.apache.jena.riot.system.PrefixMap readPrefixes(org.apache.jena.riot.system.PrefixMap sink, InputStream in, org.apache.jena.riot.Lang lang)

    • readPrefixes

      public static org.apache.jena.riot.system.PrefixMap readPrefixes(org.apache.jena.riot.system.PrefixMap sink, InputStream in, org.apache.jena.riot.Lang lang, long maxNonPrefixEventCount)
      Reads prefixes from the given input stream into the provided sink.
      Parameters:
      sink -
      in -
      lang -
      maxNonPrefixEventCount - Stop prefix scan upon encountering that many non-prefix parsing events, such as Triples. See EltStreamRDF.
      Returns:
      If the sink is null then a new prefix map is returned, otherwise the sink is returned.
