thax for your quick reply!
i has some errors in my former explanation, but you catch my idea.
Well, i use Insert(...), altought Append(...) is more appropiate.
And, again over iterators, in
template <class T, class Less> void Sort(T& c, const Less& less)
if my class T have two components, i. e.
class Point
{
float x,y
.
.
.
}
and i want to use in a class like
kdtree
{
.
. some declarations
.
}
i can employ, in a STL style, a
class PXorder{
bool operator () (point &u, point &v)
{
.
. some returns, based on if u>v or u<v
.
}
}
declared and implemented within kdtree class
but if we use
Vector<point> v;
Sort(v,PXorder());

the compiler returns ERROR: 'const PXorder' as argument 'this' in PXorder(Point,Point), discard qualifiers?
any suggestion?
PD: I will post source code later, thanx!
