将迭代器传递给另一个函数

Question

I was wondering what would be the best way to accomplish something like this...

// Iterating through a list
if ( foo ) {
  RemoveBar( it ); 
}

void RemoveBar( std::list< Type >::iterator it ) {
  it = listName.erase( it );
  ...// Other stuff related to cleaning up the removed iterator
}

I don't think pass by value will work here. Obviously what I want to do is stay in the correct iterator position when I call RemoveBar. Is pass by reference the best alternative?

Answer 1

Iterators are normally passed by value. I'd make RemoveBar() return the new iterator.
