Constructor Detail

• HeaderTokenizer

  public HeaderTokenizer(java.lang.String header,
                         java.lang.String delimiters,
                         boolean skipComments)

  Constructor that takes a rfc822 style header.

  Parameters:

  header - The rfc822 header to be tokenized

  delimiters - Set of delimiter characters to be used to delimit ATOMS. These are usually RFC822 or MIME

  skipComments - If true, comments are skipped and not returned as tokens

• HeaderTokenizer

  public HeaderTokenizer(java.lang.String header,
                         java.lang.String delimiters)

  Constructor. Comments are ignored and not returned as tokens

  Parameters:

  header - The header that is tokenized

  delimiters - The delimiters to be used

• HeaderTokenizer

  public HeaderTokenizer(java.lang.String header)

  Constructor. The RFC822 defined delimiters - RFC822 - are used to delimit ATOMS. Also comments are skipped and not returned as tokens

  Parameters:

  header - the header string

Method Detail

• next

  public HeaderTokenizer.Token next()
                             throws ParseException

  Parses the next token from this String.

  Clients sit in a loop calling next() to parse successive tokens until an EOF Token is returned.

  Returns:

  the next Token

  Throws:

  ParseException - if the parse fails

• next

  public HeaderTokenizer.Token next(char endOfAtom)
                             throws ParseException

  Parses the next token from this String. If endOfAtom is not NUL, the token extends until the endOfAtom character is seen, or to the end of the header. This method is useful when parsing headers that don't obey the MIME specification, e.g., by failing to quote parameter values that contain spaces.

  Parameters:

  endOfAtom - if not NUL, character marking end of token

  Returns:

  the next Token

  Throws:

  ParseException - if the parse fails

• next

  public HeaderTokenizer.Token next(char endOfAtom,
                                    boolean keepEscapes)
                             throws ParseException

  Parses the next token from this String. endOfAtom is handled as above. If keepEscapes is true, any backslash escapes are preserved in the returned string. This method is useful when parsing headers that don't obey the MIME specification, e.g., by failing to escape backslashes in the filename parameter.

  Parameters:

  endOfAtom - if not NUL, character marking end of token

  keepEscapes - keep all backslashes in returned string?

  Returns:

  the next Token

  Throws:

  ParseException - if the parse fails

  Since:

  JavaMail 1.5

• peek

  public HeaderTokenizer.Token peek()
                             throws ParseException

  Peek at the next token, without actually removing the token from the parse stream. Invoking this method multiple times will return successive tokens, until next() is called.

  Returns:

  the next Token

  Throws:

  ParseException - if the parse fails

• getRemainder

  public java.lang.String getRemainder()

  Return the rest of the Header.

  Returns:

  String rest of header. null is returned if we are already at end of header
