    • qualifyRecordID

      public URI qualifyRecordID(URI recordId, Map<String,String> qualifiers)
      Description copied from interface: RecordIDGenerator
      Append (or if already present, update) qualifiers to passed recordId. Use with caution. Guard against turning up a result that already exists. Use when writing a group of records inside a single transaction. How qualifiers are appended/updated varies with URI scheme. Its allowed that an invocation of this method does nought but call RecordIDGenerator.getRecordID(), returning a new URI unrelated to the passed recordId and passed qualifier.
      Specified by:
      qualifyRecordID in interface RecordIDGenerator
      Parameters:
      recordId - URI to append qualifier to.
      qualifiers - Map of qualifier values keyed by qualifier name.
      Returns:
      New URI based off passed uri and passed qualifier.
