I need to use std::lower_bound and sorting algorithms on my ContainerType.
Where (which namespace) and how can I define the operator< comparing 2
EntryType
for the std:: algorithms to use that operator?
Anywhere appropriate. Any namespace/class where your compiler is
capable of finding it.
Note I use these std::algorithms only in member functions of the C template.
So I wish to define the operator< in a way that is specific and visible only
to C template.
Have you tried defining it as a static member of the C template?
Post the rest of your code, with only the operator< missing, and we can
probably figure it out. I am just too lazy to provide all the necessary
driver code for what you've described, I consider it your job if you
want my help. Sorry, such a PITA I am.
