Hi,
I have the following code which comples:
bool contains(vector <A*>& cgl, A* cg) {
vector<A*>::ite rator iter = find_if ( cgl.begin(), cgl.end(), bind(
equal_to<A*>(), _1, cg ));
return (iter != cgl.end());
}
anb how I want to create a template of the above code:
template<class T1, class T2>
bool contains(T1& cgl, T2 cg) {
// this is line 189 of Utils.h
T1::iterator iter = find_if ( cgl.begin(), cgl.end(),
boost::lambda:: bind( equal_to<T2>(), boost::lambda:: _1, cg ));
return (iter != cgl.end());
}
but I have the compile error:
.../Utils.h: In function 'bool contains(T1&, T2)':
.../Utils.h:189: error: expected `;' before 'iter'
.../Utils.h:191: error: 'iter' was not declared in this scope
Thanks for any idea. 1 1625 ke*********@gma il.com wrote: [..] // this is line 189 of Utils.h T1::iterator iter = find_if ( cgl.begin(), cgl.end(),
You probably want to make it
typename T1::iterator iter = ...
boost::lambda:: bind( equal_to<T2>(), boost::lambda:: _1, cg ));
return (iter != cgl.end()); }
but I have the compile error: ../Utils.h: In function 'bool contains(T1&, T2)': ../Utils.h:189: error: expected `;' before 'iter' ../Utils.h:191: error: 'iter' was not declared in this scope
Thanks for any idea.

Hi all,
I was wondering if anyone had dealt with a similar problem. I need to use a
template function as the parameter for a particular function (also template
function).
The program compiles into an object file but then at the final stage it says
that it can't find template function. The platform is WindowsXP Pro, MSCV++
..Net.
More specifically what I want to do is write an atl algorithm that will also

I'm curious about what appears to be a restriction on using an STL
container inside a user-defined template, esp. using an iterator to
such a container. It's not clear to me if this is a general
template/language restriction, and STL iterator limitation, or if I'm
just going about it wrong.
I'm declaring a template which uses a std::map to store references to
the template type, e.g.
template template <typename T>

Hi all,
I'm trying to write a generic algorithm routine that will
take begin and end iterators of a container, iterate through
the range and perform a "calculation" of sorts.
The trouble is that the algorithm will behave differently for
the two different types. I've considered calling the algorithm
foo_A and foo_B, but I don't like that approach because it will
blow out in naming complexity down the track.

I need your help understanding why the following code does *NOT*
compile with G++ (tested with gcc 3.x and 4.1.x):

class myvector { // Just a simplification of std::vector
class iterator {

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
