                  int len)
           throws IOException

Writes the given byte array to the output stream in an encoded form.

Overrides:

write in class FilterOutputStream

Parameters:

b - the data to be written

off - the start offset of the data

len - the length of the data

Throws:

IOException - if an I/O error occurs

close

public void close()
           throws IOException

Closes the stream, this MUST be called to ensure proper padding is written to the end of the output stream.

Specified by:

close in interface Closeable

Overrides:

close in class FilterOutputStream

Throws:

IOException - if an I/O error occurs

encode

public static String encode(String unencoded)

Returns the encoded form of the given unencoded string.

Parameters:

unencoded - the string to encode

Returns:

the encoded form of the unencoded string
