class CParserVCal : public CVersitParser

/** A vCalendar parser.

Adds support for parsing vToDos and vEvents, and associated alarms 

(see CParserPropertyValueAlarm) to the functionality of CVersitParser.

Adds a constructor and overrides CVersitParser::InternalizeL() for streams, 

ExternalizeL() for streams, RecognizeToken(), RecognizeEntityName() and MakeEntityL().

The vCalendar data is read from or written to a stream or file, using the 

InternalizeL() and ExternalizeL() functions. Most users of this class will 

only need to use these functions.

Note: if you are sequentially creating and destroying multiple 

parsers, a major performance improvement may be achieved by using thread local 

storage to store an instance of CVersitUnicodeUtils which persists and can be 

used by all of the parsers.

See CVersitTlsData for more information.
