2d hash_map iteration ?

Greetings,

I have a 2D hash_map, defined as follows:

typedef hash_map<const char*,
str_session,
hash<const char*>,
eqstr> t_hashchar;
typedef hash_map<const char*,
t_hashchar,
hash<const char*>,
eqstr> t_hashcharchar;

so it is hash[const char*][const char*] = str_session
(in the context used, its hash["username"]["sessionid"] = str_session)

I am attempting to write an outer loop that iterates through the
username's, and an inner loop that iterates through the session id's
for that username.

The code that I have doing this is as follows:

void results(t_hashc harchar &h) {
t_hashcharchar: :iterator x;
t_hashchar::ite rator y;

for (x = h.begin(); x != h.end(); x++) {
for (y = x->begin(); y != x->end(); y++) {
// do stuff
}
}
}

but gives me compilation errors.

I'm either (more than likely) not understanding something properly, or
am missing something blatently obvious.

Could someone please help point out the obvious to me, or guide me towards
finding a way to do this?

Thanks!

Kristofer

Hi there, I would much appreciate your help with the following problem. Below is the code that uses a hash_map. I want to release all the memory occupied by the hash_map for other use. Apparently clear() function is not working and the trick with swap() is half working. Does anybody know how to deallocate the hash_map? Thanks in advance. Kon #include <functional>

Hi All, I am developing my code with Apache stdcxx. I am bound to use STL of Apache only. Now today I need hash_map in code but as I learned, it is not available in Apache since it is not standard c++. Though it is available with GNU STL. The code module where I use hash_map will generate separate object file during compilation. This code module is also using STL string.

Hi, I am wondering if there are any functional differences between SGI's hash_map and tr1's unordered_map. Can these two containers be interchanged? What would it take to switch from hash_map to unordered_map? Thank you. -Marek
