class CParserVCard : public CVersitParser

/** A vCard parser. 

Adds support for property groups (see CParserGroupedProperty) and agents 

(see CParserPropertyValueAgent) to the functionality of CVersitParser. 

Provides a constructor and overrides CVersitParser::InternalizeL(),   

ExternalizeL(), RecognizeToken(), ConvertAllPropertyDateTimesToMachineLocalL(), 

ParsePropertyL() and MakePropertyValueL().

The vCard 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.

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.

// CParserGroupedProperty

//

class CParserGroupedProperty : public CParserProperty

/** A grouped property.

This is a vCard property which may be a member of one or more property groups. 

It owns an array of descriptors, each of which identifies a group 

to which the property belongs.

An example of how grouped properties may be useful is for a person with two 

homes. Each home has an address and telephone number, both of which are to 

be stored on the vCard. The address and telephone number are grouped for each 

home. A prefix for the address and telephone number properties is provided: 

one for each home. Each prefix is stored as a property group.

When the property is externalised, the identities of all the groups to which 

the property belongs (i.e. the prefixes) are written to the stream before 

CParserProperty::ExternalizeL() is called.

The class also provides a function which can be used to test whether 

the property is a member of a given group.

Note that the vCard parser stores all properties using this class; if the 

vCard property is not grouped then the array of property groups is empty. 

Conversely, the vCalender parser does not have property groups, and so stores 

all properties using the CParserProperty base class.
