OOP: Better OOP part 5a 2003-04-21 -- Dan Pressnell Newsgroups: comp.lang.clarion,topspeed.topic.oop
March 5, 2006:
Note that the code is now available at:
http://www.icetips.com/downloadfile.php?FileID=59
I've been asked if it's possible for a queue in a class to be derived from a
file record structure. It's easy to do:
myclass class, type
q &myqueueytpe
end
myqueuetype queue(fil:record), type, pre(myqueuetype)
end
When using, use dot notation, such as:
myclass.q.myfield1
When including the INC file, place the include in the embed after the file
declarations, so it will compile.
Also, because the queue type declaration will get included whenever you
include the INC file, every app that includes the class will have to know
the file structure the queue is derived from, which will often be the case.
