Method Detail

encodeRFC2231value

protected static boolean encodeRFC2231value(String value,
                         StringBuilder buf)

Encodes a value per RFC 2231.

This is used to pass non-ASCII parameters to MIME parameter lists.

This implementation always uses UTF-8 and no language.

See RFC 2231 for details.

Parameters:

value - the value to encode

buf - the buffer to fill

Returns:

true if an encoding was needed, or false if no encoding was actually needed

encodeRFC2231

protected static String encodeRFC2231(String key,
                   String value)

Encodes a MIME parameter per RFC 2231.

This implementation always uses UTF-8 and no language.

See RFC 2231 for details.

Parameters:

value - the string to encode

Returns:

the encoded string

encodeContentDisposition

public static String encodeContentDisposition(String disposition,
                              String filename)

Encodes the Content-Disposition header value according to RFC 2183 and RFC 2231.

See RFC 2231 for details.

Parameters:

disposition - the disposition

filename - the file name

Returns:

the encoded header value

decodeContentDispositionFilename

public static String decodeContentDispositionFilename(String value)

Decodes a filename from the Content-Disposition header value according to RFC 2183 and RFC 2231.

See RFC 2231 for details.

Parameters:

value - the header value to decode

Returns:

the filename

decodeContentDisposition

public static String decodeContentDisposition(String value,
                              Map<String,String> params)

Decodes the Content-Disposition header value according to RFC 2183 and RFC 2231.

Does not deal with continuation lines.

See RFC 2231 for details.

Parameters:

value - the header value to decode

params - the map of parameters to fill

Returns:

the disposition

getCharsetFromContentType

public static String getCharsetFromContentType(String value)

Gets charset from a content type header.

Parameters:

value - the header value to decode

Returns:

the charset or null if no valid boundary available

getBoundaryFromMultiPart

public static byte[] getBoundaryFromMultiPart(String value)

Gets the boundary from a multipart/formdata content type header.

Parameters:

value - the header value to decode

Returns:

the boundary as a byte array or null if no valid boundary available

getParameters

protected static Map<String,String> getParameters(String list,
                               Map<String,String> params)
                                           throws MimeHelper.ParseException

Throws:

MimeHelper.ParseException
