Handling of various input and output formats
The three main classes involved in the format handling are:- FormatFactory: creating format implementation instances
- InputFormat: base interface for input format handlers
- OutputFormat: base interface for output format handlers
Implementations of the InputFormat interface read the text data from an C++ input stream and parse it for contact data according to the format they implement.
Implementations of the OutputFormat interface format the contact data into a pure text form according to the format they implement and then write this to a C++ output stream
Both kinds of implementations need to be added to the FormatFactory so they can be created by name.
