Constructor Detail

Method Detail

parse

public SIPHeader parse()
                throws ParseException

parse the message. Note that we have losened up on the parsing quite a bit because user agents tend to be very bad about specifying the user agent according to RFC.

Overrides:

parse in class HeaderParser

Returns:

SIPHeader (UserAgent object)

Throws:

SIPParseException - if the message does not respect the spec.

ParseException - if there was an error parsing.

main

public static void main(String[] args)
                 throws ParseException

Throws:

ParseException
