Operator Overinding

[Mongoose7]

Hi everyone,

Ive been trying to overload the insertion and extration operators (<<
and >>) without much success... What I need to do is

override a general cout << anyvar << anyvar

with a overriddden method that adds a timestamp to the cout.

[Timestamp] anyvar anyvar

OR

is it possible to mess around with streams so that I can actually
stream something through a class of my own, like

myclass << somevar

Thanks!

One simple approach is to create a manipulator class that will put the
stamp and the syntax would look like:

std::cout << stamp() << anyvar << anyvar;

Another more advanced approach is to use a custom streambuf which will
track ends of lines and insert stamping for you. Google groups for
filtering streambuf.

Yes, it's pretty easy to wrap and std:stream into your own class with a
templated operatro<<(T const&) which does needed profixing and postfixing
and forward t to operator<<(std:stream&, T).

Hey thanks! Ill give the second approach a try.
