I am trying to think of an efficient way of implementing a
logging system for a big program. My thoughts are to create a
message logging base class and letting all objects that need
logging ability inherit from this base class along with the
other base classes they inherit from. This should work (not
sure how efficient it is though) but I want to share the data
structure that keeps the log messages between all the classes
that's inherited from this base class. (This data structure
will either be written to the disk, displayed using message
boxes or added to a tree view type of class in the main GUI).
To do this, I am thinking to declare the data structure as
static, but I'm not sure if this will do the trick...
It doesn't really make sense, any more than having every class
inherit from a class Object makes sense. Everything is, or
should be "loggable" (including things like int, which can't
derive from a LoggableObject class).
Any idea if this will work? If not, a global data structure
can probably do the trick I don't want to do that. Is there
maybe a simpler way of doing this type of thing?
Logging is a global service, which means at some level, you
always end up with some sort of "global" object. Usually
several, in fact.
