The latest version of this topic can be found at operator<= (multimap) (STL/CLR).
List less than or equal comparison.
Syntax
template<typename Key,
typename Mapped>
bool operator<=(multimap<Key, Mapped>% left,
multimap<Key, Mapped>% right);
Parameters
left
Left container to compare.
right
Right container to compare.
Remarks
The operator function returns !(``right < left``). You use it to test whether left is not ordered after right when the two multimaps are compared element by element.
Example
// cliext_multimap_operator_le.cpp
// compile with: /clr
#include <cliext/map>
typedef cliext::multimap<wchar_t, int> Mymultimap;
int main()
{
Mymultimap c1;
c1.insert(Mymultimap::make_value(L'a', 1));
c1.insert(Mymultimap::make_value(L'b', 2));
c1.insert(Mymultimap::make_value(L'c', 3));
// display contents " [a 1] [b 2] [c 3]"
for each (Mymultimap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
// assign to a new container
Mymultimap c2;
c2.insert(Mymultimap::make_value(L'a', 1));
c2.insert(Mymultimap::make_value(L'b', 2));
c2.insert(Mymultimap::make_value(L'd', 4));
// display contents " [a 1] [b 2] [d 4]"
for each (Mymultimap::value_type elem in c2)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
System::Console::WriteLine("[a b c] <= [a b c] is {0}",
c1 <= c1);
System::Console::WriteLine("[a b d] <= [a b c] is {0}",
c2 <= c1);
return (0);
}
[a 1] [b 2] [c 3]
[a 1] [b 2] [d 4]
[a b c] <= [a b c] is True
[a b d] <= [a b c] is False
