An object stores itself by externalizing its data to one or more streams using the write stream interface and restores itself by internalizing from the same streams using the read stream interface.</p> <p>An instance of a class can be externalized to a stream, and internalized from a stream, by adding definitions and implementations for the two functions, <codeph>InternalizeL()</codeph> and <codeph>ExternalizeL()</codeph> to that class.</p> <p>A class that defines and implements these functions is a store-aware class.</p> </conbody></concept>
