operator< (multimap) (STL/CLR)
List less than comparison.
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 true if, for the lowest position i for which !(right[i] < left[i]) it is also true that left[i] < right[i]. Otherwise, it returns left->size() < right->size() You use it to test whether left is ordered before right when the two multimaps are compared element by element.
Example
// cliext_multimap_operator_lt.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 c] < [a b d] is {0}",
c1 < c2);
return (0);
}
[a 1] [b 2] [c 3] [a 1] [b 2] [d 4] [a b c] < [a b c] is False [a b c] < [a b d] is True
