javax.mail.internet Class HeaderTokenizer

java.lang.Object
  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.

This class handles folded headers (ie headers with embedded CRLF SPACE sequences). The folds are removed in the returned tokens.

方法摘要
`String`	`getRemainder()` Return the rest of the Header.
`HeaderTokenizer.Token`	`next()` Parses the next token from this String.
`HeaderTokenizer.Token`	`peek()` Peek at the next token, without actually removing the token from the parse stream.

构造器详细信息

HeaderTokenizer

public HeaderTokenizer(String header,
                       String delimiters,
                       boolean skipComments)

Constructor that takes a rfc822 style header.

参数:: 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

参数:: 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

方法详细信息

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.

返回:: the next Token
抛出异常:: 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.
