Where to put typedef std::map<key,val>....

[tomix]

Hi,
I have a domain model written with STL and a client which uses it
I would like to give the client a better way to declare a container.
Where is the best place to put all my typedefs?
(typedef list <EnrollInfoEnrollInfoList)

Thanks in advance.

We have no idea. You'll have to give us more specific information about
how the code is laid out. Generally, you'll want to put types,
constants, and variables at the smallest (i.e., most nested) scope you
can.

Assuming I have a domain model with students ,lecturers ,courses and
,course offers

And most of classes have a method which return list<EnrollInfo*>&,
In the client many function uses those methods.

Defining the type in the domain model seems to me the way to go
Maybe i just can encapsulate them in a namespace? or just put them in a
header file?
Thanks in advance.

Please don't top-post (see
<http://parashift.com/c++-faq-lite/how-to-post.html#faq-5.4>). I've
fixed it for you here.

I would suggest:

const list< some_smart_ptr<EnrollInfo& instead.

If it's not const here, why hide it behind member functions in the
object that owns it? Using a smart pointer (e.g., std::tr1::shared_ptr
aka boost::shared_ptr) here makes your list exception-safe and provides
automatic cleanup while still allowing for polymorphic usage.

Show us more code (see the guidelines on posting code here:
<http://parashift.com/c++-faq-lite/how-to-post.html#faq-5.8>).
