list::clear (STL/CLR)
Removes all elements.
void clear();
Remarks
The member function effectively calls list::erase (STL/CLR)( list::begin (STL/CLR)(), list::end (STL/CLR)()). You use it to ensure that the controlled sequence is empty.
Example
// cliext_list_clear.cpp
// compile with: /clr
#include <cliext/list>
int main()
{
cliext::list<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);
}
a b c size() = 0 a b size() = 0
