Method Details

getName

public String getName()

Specified by:

getName in class Encoding

encode

public String encode(byte[] in)
              throws EncodingException

This will split multibyte chars across lines, see 4th ref above

Specified by:

encode in class Encoding

Returns:

Encoded string.

Throws:

UnsupportedOperationException - always

EncodingException

encode

public String encode(String str)
              throws EncodingException

Encode a single header line ONLY. Do NOT include the \r\n. Returns a string of one or more lines including the trailing \r\n. Field-name will not be encoded, must be less than 62 chars. The fieldBody is treated as "unstructured text", which is suitable only for the field names "Subject" and "Comments". We do NOT tokenize into structured fields. To make things easy, we either encode the whole field body as RFC 2047, or don't encode at all. If it's too long for a single line, we encode it, even if we didn't otherwise have to. We don't do quoted-string. This will not split multibyte chars, including supplementary chars, across lines. TODO this will not work for quoting structured text such as recipient names on the "To" and "Cc" lines.

Overrides:

encode in class Encoding

Parameters:

str - must start with "field-name: ", must have non-whitespace after that

Throws:

EncodingException
