Create a template which declares STL iterator

[ken.carlino@gmail.com]

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.

You probably want to make it

typename T1::iterator iter = ...
