priority_queue : : top_item (STL/CLR)
Accesses the highest-priority element.
property value_type back_item;
Notes
The property accesses the top (highest-priority) element of the controlled sequence, which must be non-empty. You use it to read or write the highest-priority element, when you know it exists.
Exemple
// cliext_priority_queue_top_item.cpp
// compile with: /clr
#include <cliext/queue>
typedef cliext::priority_queue<wchar_t> Mypriority_queue;
int main()
{
Mypriority_queue c1;
c1.push(L'a');
c1.push(L'b');
c1.push(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// inspect last item
System::Console::WriteLine("top_item = {0}", c1.top_item);
// alter last item and reinspect
c1.top_item = L'x';
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
