  • All Implemented Interfaces:
    TopicMapReaderIF
    public class RDFTopicMapReader
extends Object
implements TopicMapReaderIF
    PUBLIC: Converts an RDF model to a topic map using a schema-specific mapping defined using RDF. The mapping is taken from the RDF model unless a different model is specifically indicated to contain the mapping.

      • 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 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.

      • 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.
        Throws:
        IOException
