public static java.util.Map<java.lang.String,java.lang.String> getHeaderParams(java.lang.String pValue)
Parses a complex field value into a map of key/value pairs. You may use this, for example, to parse a definition like
text/plain; charset=UTF-8; boundary=foobarThe above example would return a map with the keys "", "charset", and "boundary", and the values "text/plain", "UTF-8", and "foobar".
Header value will be unfolded and excess white space trimmed.
pValue
- The field value to parse.public static java.lang.String createUniqueBoundary()
public static java.lang.String createUniqueMessageId(java.lang.String hostName)
null
it will be used as suffix for the message ID
(following an at sign).
The resulting string is enclosed in angle brackets (< and >);hostName
- host name to be included in the message ID or
null
if no host name should be included.public static java.lang.String formatDate(java.util.Date date, java.util.TimeZone zone)
date
- date to be formatted into a string.zone
- the time zone to use or null
to use the default
time zone.public static java.lang.String fold(java.lang.String s, int usedCharacters)
s
- string to split.usedCharacters
- number of characters already used up. Usually the number of
characters for header field name plus colon and one space.public static java.lang.String unfold(java.lang.String s)
s
- string to unfold.Copyright © 2004-2014. All Rights Reserved.
