Examples of java.io.PrintWriter.checkError()

java.io.PrintWriter.checkError()
Answers a boolean indicating whether or not this PrintWriter has encountered an error. If so, the receiver should probably be closed since further writes will not actually take place. A side effect of calling checkError is that the target Writer is flushed. @return boolean has an error occurred in this PrintWriter.

    {
      writer.flush();
      writer.close();


      // Check for errors
      if (writer.checkError())
      {
        if (file.exists())
          file.delete();


        _error(_XML_ENCODING_ERROR + path);
