The auto text function can be used to organize reusable text passages. They allow storing text, including the formatting and all other contents in a text block collection to apply them later. Three services deal with auto text in

  /** Insert an autotext at the current cursor position of given cursor mxDocCursor*/
  // Get an XNameAccess interface to all auto text groups from the document factory
  XNameAccess xContainer = (XNameAccess) UnoRuntime.queryInterface( 
      XNameAccess.class, mxFactory.createInstance(""));
  // Get the autotext group Standard
  xGroup = (XAutoTextGroup) UnoRuntime.queryInterface(
      XAutoTextGroup.class, xContainer.getByName("Standard"));
  // get the entry Best Wishes (BW)
  XAutoTextEntry xEntry = (XAutoTextEntry)UnoRuntime.queryInterface ( 
      XAutoTextEntry.class, xGroup.getByName ("BW"));
  // insert the modified autotext block at the cursor position
  /** Add a new autotext entry to the AutoTextContainer
  // Select the last paragraph in the document
  // Get the XAutoTextContainer interface of the AutoTextContainer service
  XAutoTextContainer xAutoTextCont = (XAutoTextContainer) UnoRuntime.queryInterface(
      XAutoTextContainer.class, xContainer );
  // If the APIExampleGroup already exists, remove it so we can add a new one
  if (xContainer.hasByName("APIExampleGroup"))
      xAutoTextCont.removeByName("APIExampleGroup" );
  // Create a new auto-text group called APIExampleGroup
  XAutoTextGroup xNewGroup = xAutoTextCont.insertNewByName ( "APIExampleGroup" );
  // Create and insert a new auto text entry containing the current cursor selection
  XAutoTextEntry xNewEntry = xNewGroup.insertNewByName(
      "NAE", "New AutoTextEntry", xParaCursor);
  // Get the XSimpleText and XText interfaces of the new autotext block
  XSimpleText xSimpleText = (XSimpleText) UnoRuntime.queryInterface(
      XSimpleText.class, xNewEntry);
          XText xText = (XText) UnoRuntime.queryInterface(XText.class, xNewEntry);
  // Insert a string at the beginning of the autotext block
      "This string was inserted using the API!\n\n", false);

The current implementation forces the user to close the AutoTextEntry instance when they are changed, so that the changes can take effect. However, the new AutoText is not written to disk until the destructor of the AutoTextEntry instance inside the writer is called. When this example has finished executing, the file on disk correctly contains the complete text "This string was inserted using the API!\n\nSome text for a new autotext block", but there is no way in Java to call the destructor. It is not clear when the garbage collector deletes the object and writes the modifications to disk.
