net.ontopia.topicmaps.utils.rdf.RDFTopicMapWriter
All Implemented Interfaces:
TopicMapWriterIF
public class RDFTopicMapWriter extends Object implements TopicMapWriterIF

    • RDFTopicMapWriter

      public RDFTopicMapWriter(Writer writer)
      PUBLIC: Creates a writer that writes the RDF representation to the given OutputStream serialized to RDF/XML.

    • RDFTopicMapWriter

      public RDFTopicMapWriter(org.apache.jena.rdf.model.Model model)
      PUBLIC: Creates a writer that builds an RDF representation of the topic map in the given Jena RDF model.

  • Method Details

    • setPreserveScope

      public void setPreserveScope(boolean preserve_scope)
      PUBLIC: Controls whether the writer will use RDF reification to preserve the scopes in the topic map.

    • getPreserveScope

      public boolean getPreserveScope()
      PUBLIC: Returns true if the writer will use RDF reification to preserve the scopes in the topic map.

    • setPreserveReification

      public void setPreserveReification(boolean preserve_reification)
      PUBLIC: Controls whether the writer will use RDF reification to preserve reification in the topic map.

    • getPreserveReification

      public boolean getPreserveReification()
      PUBLIC: Returns true if the writer will use RDF reification to preserve reification in the topic map.

    • setFilter

      public void setFilter(Predicate filter)
      PUBLIC: Sets the filter that decides which topic map constructs are accepted and exported. Uses 'filter' to identify individual topic constructs as allowed or disallowed. TM constructs that depend on the disallowed topics are also disallowed.
      Parameters:
      filter - Places constraints on individual topicmap constructs.

    • write

      public void write(TopicMapIF topicmap)
      Description copied from interface: TopicMapWriterIF
      PUBLIC: Writes the given topic map to an implicit implementation dependent destination. The write method will close any resources opened internally. This means that the write method can only be called once if the stream/writer was opened internally.
      Specified by:
      write in interface TopicMapWriterIF
      Parameters:
      topicmap - The topic map to be exported/written; an object implementing TopicMapIF
