Class HeaderTokenizer

java.lang.Object
  extended by javax.mail.internet.HeaderTokenizer

public class HeaderTokenizer
extends Object

This class tokenizes RFC822 and MIME headers into the basic symbols specified by RFC822 and MIME.

HeaderTokenizer

public HeaderTokenizer(String header,
                       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(String header,
                       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(String header)
Constructor. The RFC822 defined delimiters - RFC822 - are used to delimit ATOMS. Also comments are skipped and not returned as tokens

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

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 String getRemainder()
Return the rest of the Header.

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