    • LTMTopicMapWriter

      public LTMTopicMapWriter(File file) throws IOException
      PUBLIC: Create an LTMTopicMapWriter that writes to a given File in UTF-8.
      Parameters:
      file - Where the output should be written to.
      Throws:
      IOException

    • LTMTopicMapWriter

      public LTMTopicMapWriter(File file, String encoding) throws IOException
      PUBLIC: Create an LTMTopicMapWriter that writes to a given File in specified encoding.
      Parameters:
      file - Where the output should be written to.
      encoding - The desired character encoding.
      Throws:
      IOException

    • LTMTopicMapWriter

      public LTMTopicMapWriter(OutputStream stream) throws IOException
      PUBLIC: Create an LTMTopicMapWriter that writes to a given OutputStream in UTF-8. Warning: Use of this method is discouraged, as it is very easy to get character encoding errors with this method. Note: Caller is responsible for closing the stream!
      Parameters:
      stream - Where the output should be written.
      Throws:
      IOException

    • LTMTopicMapWriter

      public LTMTopicMapWriter(OutputStream stream, String encoding) throws IOException
      PUBLIC: Create an LTMTopicMapWriter that writes to a given OutputStream in the given encoding. Note: Caller is responsible for closing the stream!
      Parameters:
      stream - Where the output should be written.
      encoding - The desired character encoding.
      Throws:
      IOException

    • LTMTopicMapWriter

      public LTMTopicMapWriter(Writer out, String encoding)
      PUBLIC: Create an LTMTopicMapWriter that writes to a given Writer. Note: Caller is responsible for closing the writer!
      Parameters:
      out - Where the output should be written.
      encoding - The encoding used by the writer. This is the encoding that will be declared on the first line of the LTM file. It must be reported, because there is no way for the LTMTopicMapWriter to know what encoding the writer uses.

    • setPreserveIds

      public void setPreserveIds(boolean preserveIds)
      PUBLIC: Set whether IDs should be preserved or generated.
      Parameters:
      preserveIds - Should be set to true if IDs should be preserved.

    • setFilter

      public void setFilter(Predicate<Object> filter)
      PUBLIC: Sets the filter that decides which topic map constructs are accepted in the exprted ltm. 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.

    • addPrefix

      public boolean addPrefix(String key, String prefix)

      PUBLIC: Writes out the given topic map.
      Specified by:
      write in interface TopicMapWriterIF
      Parameters:
      tm - The topic map to be exported/written; an object implementing TopicMapIF
      Throws:
      IOException - Thrown if writing the topic map fails.
