insertString

public void insertString(int offs,
                         String str,
                         AttributeSet a)
                  throws BadLocationException

    Inserts some content into the document. Inserting content
    causes a write lock to be held while the actual changes are
    taking place, followed by notification to the observers on
    the thread that grabbed the write lock.

    This method is thread safe, although most Swing methods are
    not. Please see Threads and Swing for more information.
