/** 

Abstract base class for classes that handle storage of WAP Push Messages in 

the message server.

The class acts as a wrapper for TMsvEntry, and provides accessors and storage 

functionality. Key pieces of data are mapped onto certain TMsvEntry fields: 

this speeds up access by applications to this data. This base class has the 

generic mappings and storage behaviour. More specialised mappings and storage 

are defined in each derived class.

The mappings of data to TMsvEntry fields standard to all classes are:

Push Message Type UID: TMsvEntry::iBioType

Status: sets bits 0-3 of TMsvEntry::iMtmData1

Some derived classes need to store more data than there are available fields 

in TMsvEntry, and the Unknown type potentially requires large data capacity. 

This additional data is saved in the message store associated with the message 

entry. Derived classes provide this functionality by overriding ExternalizeL() 

and InternalizeL() implementations. The base class itself uses the message store

to store the WAP Push message's raw header and From information.
