Detailed Description

Abstract base class for all formatters.

Formatters map Persistable subclasses into an appropriate form for output to Storage subclasses and vice versa upon retrieval. They also may use an additional piece of data to select the appropriate data for retrieval.

Subclasses of Formatter must register themselves by creating a static instance of the FormatterRegistration class with the name and type_info of the Persistable class they are formatting and a factory method to create instances of the subclass using a Policy. If they are to be used with boost::serialization, subclasses of Formatter must also implement a public static delegateSerialize() template (or a set of static delegateSerialize() functions for each supported archive type).
