vector::clear (STL/CLR)
Supprime tous les éléments.
void clear();
Notes
La fonction membre appelle efficacement vector::erase (STL/CLR)(vector::begin (STL/CLR)(),vector::end (STL/CLR)()).Vous l'utilisez pour garantir que la séquence contrôlée est vide.
Exemple
// cliext_vector_clear.cpp
// compile with: /clr
#include <cliext/vector>
int main()
{
cliext::vector<wchar_t> c1;
c1.push_back(L'a');
c1.push_back(L'b');
c1.push_back(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// clear the container and reinspect
c1.clear();
System::Console::WriteLine("size() = {0}", c1.size());
// add elements and clear again
c1.push_back(L'a');
c1.push_back(L'b');
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
c1.clear();
System::Console::WriteLine("size() = {0}", c1.size());
return (0);
}
