  • Method Details

    • buildTimeZone

      public static SimpleTimeZone buildTimeZone(String ical)
      Builds a Java TimeZone from the VTIMEZONE info in an iCal file.
      Returns:
      a Java TimeZone that matches the iCal one, or NULL if no TZ info present

    • buildTimeZone

      protected static SimpleTimeZone buildTimeZone(Map<String,String> icalParams)
      Internal version that takes the parameters from getICalParams(String) and builds a TimeZone from it. This is not public as it will be refactored when getICalParams(String) is replaced. Note - because it uses the icalParams, we can't handle cases where we're given historic TZ info (eg until 2004 it was that, now it's this)

    • icalLineKeyValue

      protected static String[] icalLineKeyValue(String icalLine)
      Splits an iCal line into key and value by the first unquoted colon.
      Parameters:
      icalLine - String

    • getICalParams

      protected static Map<String,String> getICalParams(String icalText)
      Turns an iCal event into event + timezone parameters. This is very closely tied to the SPP / VTI implementation, and should be replaced with something more general. Until then, it is deliberately not public.
      Parameters:
      icalText - iCal text for the event, and the TZ (prefixed)
