The numbers in the annotations below refer to the numbered elements of the listing above.

Ê Since this compilation unit implements the MyEventProcessor class, it is necessary for the ﬁle to

have access to the header for that class.

Ë The header for MyEventProcessor declared several classes to be forward deﬁned. Since these

classes will be manipulated in the implementation module, the headers for these classes must now

be #include-ed.
