swing Serializzazione di DefaultStyledDocument in RTF


Esempio

Utilizzando la libreria AdvancedRTFEditorKit è possibile serializzare un documento DefaultStyledDocument su una stringa RTF.

try {
   DefaultStyledDocument writeDoc = new DefaultStyledDocument();
   writeDoc.insertString(0, "Test string", null);
      
   AdvancedRTFEditorKit kit = new AdvancedRTFEditorKit();
   //Other writers, such as a FileWriter, may be used
   //OutputStreams are also an option
   Writer writer = new StringWriter();
   //You can write just a portion of the document by modifying the start
   //and end indexes
   kit.write(writer, writeDoc, 0, writeDoc.getLength());
   //This is the RTF String
   String rtfDoc = writer.toString();
     
   //As above this may be a different kind of reader or an InputStream
   StringReader reader = new StringReader(rtfDoc);
   //AdvancedRTFDocument extends DefaultStyledDocument and can generally
   //be used wherever DefaultStyledDocument can be.
   //However for reading, AdvancedRTFDocument must be used
   DefaultStyledDocument readDoc = new AdvancedRTFDocument();
   //You can insert at different values by changing the "0"
   kit.read(reader, readDoc, 0);
   //readDoc is now the same as writeDoc
} catch (BadLocationException | IOException ex) {
    //Handle exception
    ex.printStackTrace();
