The type of a constant reference to an element.
typedef value_type% const_reference;
Remarks
The type describes a constant reference to an element.
Example
// cliext_hash_map_const_reference.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_map<wchar_t, int> Myhash_map;
int main()
{
Myhash_map c1;
c1.insert(Myhash_map::make_value(L'a', 1));
c1.insert(Myhash_map::make_value(L'b', 2));
c1.insert(Myhash_map::make_value(L'c', 3));
// display contents " [a 1] [b 2] [c 3]"
Myhash_map::const_iterator cit = c1.begin();
for (; cit != c1.end(); ++cit)
{ // get a const reference to an element
Myhash_map::const_reference cref = *cit;
System::Console::Write(" [{0} {1}]", cref->first, cref->second);
}
System::Console::WriteLine();
return (0);
}
[a 1] [b 2] [c 3]
