Class DeMIME

java.lang.Object
  au.gov.tas.dpiwe.mr.tool.DeMIME

public class DeMIME
extends Object

This tool extracts all MIME sections from a file, using Mr Architecture's ByteCharTranscoder for base64 parts. (Note: quoted-printable is not yet supported - the output is an eml file with the quotes intact.)

The encoded output is echoed as it is read.

Since:

Mr Architecture 3.3

Version:

1.0.0.0

DeMIME

public DeMIME()

Method Detail

main

public static void main(String[] argv)
                 throws Exception

Initiates the DeMIME tool.

Parameters:

argv - first argument is a filename.

Throws:

IOException - if the input file could not be read or the output file could not be written.

Exception - if something else goes wrong.

deMIME

public static boolean deMIME(Reader input)
                      throws IOException

Produces output files from an input containing MIME multipart sections.

Parameters:

input - the MIME multipart input, with encoded sections prefixed by "Content-Transfer-Encoding:" and "Content-Type:".

Returns:

if at least one output file was decoded, false otherwise.

Throws:

IOException - if the decoding could not proceed for whatever reason.

deBase64Block

public static void deBase64Block(BufferedReader input,
                                 OutputStream output)
                          throws IOException

Produces a single output files from an input containing base 64 encoded lines. Termination is at the first blank line. Non-base-64-encoded lines produce an IOException.

Parameters:

input - the base 64 input.

output - somewhere to write the decoded data.

Throws:

IOException - if the decoding could not proceed for whatever reason.

otherBlock

public static void otherBlock(BufferedReader input,
                              OutputStream output)
                       throws IOException

Produces a single output file from an input containing non-MIME boundary lines. Termination is at the first boundary line or EOF.

Parameters:

input - the 7-bit clear input.

output - somewhere to write the decoded data.

Throws:

IOException - if the decoding could not proceed for whatever reason.
