public CalendarTimezoneHelper()

Method Detail

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)
