Method and apparatus for implementing persistent data in object-oriented programs.
A class declaration is separated into two parts, a first structure type for storage
of one or more data values, and a class that derives from the structure type. Objects
of the structure type are instantiated and initialized in the source program. The
class definition includes a static method that converts an object of the structure
type to an instance of the class in response to a reference to the method. Thereby,
memory for the objects is allocated and data values are assigned to the objects
at compile-time.
