  Parameters:

  dh - the data handler with the content to encode

  Returns:

  the base64 encoded content

  Throws:

  IOException - if an I/O error occurs when reading the content of the data handler

• encodeToCharArray

  public static char[] encodeToCharArray(javax.activation.DataHandler dh)
                                  throws IOException

  Get a base64 representation of the content of a given DataHandler as a char array. This method will try to carry out the encoding operation in the most efficient way.

  Parameters:

  dh - the data handler with the content to encode

  Returns:

  the base64 encoded content

  Throws:

  IOException - if an I/O error occurs when reading the content of the data handler

• decode
