    • read

      public TopicMapIF read() throws IOException
      Description copied from interface: TopicMapReaderIF
      PUBLIC: Reads the next topic map available from some implicit, implementation dependent source.

      A topic map source may contain multiple topic maps. The read method returns the next topic map that is available from that source. null is returned when there are no more topic maps available. In a sense this is iterator-like behaviour.

      Specified by:
      read in interface TopicMapReaderIF
      Returns:
      The next topic map read from the source; an object implementing TopicMapIF. null is returned when there are no more topic maps available from the source.
      Throws:
      IOException - Thrown if reading the source fails.

    • readAll

      public Collection<TopicMapIF> readAll() throws IOException
      Description copied from interface: TopicMapReaderIF
      PUBLIC: Reads all the topic map available from some implicit, implementation dependent source.

      A topic map source may contain multiple topic maps. The readAll method returns a collection contain all the topic maps available from the source.

      Specified by:
      readAll in interface TopicMapReaderIF
      Returns:
      A collection containing all the topic maps read from the source; objects implementing TopicMapIF.
      Throws:
      IOException - Thrown if reading the source fails.

    • setAdditionalProperties

      public void setAdditionalProperties(Map<String,Object> properties)
      RDBMSTopicMapReader does not accept any additional properties outside of the specified properties file.

      Parameters:
      properties -

    • importInto

      public void importInto(TopicMapIF topicmap) throws IOException
      Description copied from interface: TopicMapReaderIF
      PUBLIC: Imports an implicitly designated topic map into the given topic map.
      Specified by:
      importInto in interface TopicMapReaderIF
      Parameters:
      topicmap - The topic map into which the import will be done; an object implementing TopicMapIF.
