 <div class="block">A helper class for generating formatted text. StackWriter keeps track of
  nested formatting state like indentation level and quote escaping. Typically,
  it is inserted between a PrintWriter and the real Writer; directives are
  passed straight through the PrintWriter via the write method, as in the
  following example:

  <blockquote><pre><code>
     StringWriter sw = new StringWriter();
     StackWriter stackw = new StackWriter(sw, StackWriter.INDENT_SPACE4);
     PrintWriter pw = new PrintWriter(stackw);
     pw.write(StackWriter.INDENT);
     pw.print("execute remote(link_name,");
     pw.write(StackWriter.OPEN_SQL_STRING_LITERAL);
     pw.println();
     pw.write(StackWriter.INDENT);
     pw.println("select * from t where c &gt; 'alabama'");
     pw.write(StackWriter.OUTDENT);
     pw.write(StackWriter.CLOSE_SQL_STRING_LITERAL);
     pw.println(");");
     pw.write(StackWriter.OUTDENT);
     pw.close();
     System.out.println(sw.toString());
  </code></pre></blockquote>

  <p>which produces the following output:

  <blockquote><pre><code>
       execute remote(link_name,'
           select * from t where c &gt; ''alabama''
       ');
  </code></pre></blockquote></div>
