insert_iterator::operator=

Inserts a value into the container and returns the iterator updated to point to the new element.

insert_iterator<Container>& operator=(
   typename Container::const_reference _Val,
);
insert_iterator<Container>& operator=(
   typename Container::value_type&& _Val
); 

매개 변수

• _Val
  The value to be assigned to the container.

반환 값

A reference to the element inserted into the container.

설명

The first member operator evaluates

Iter = container->insert(Iter, _Val);

++Iter;

then returns *this.

The second member operator evaluates

Iter = container->insert(Iter, std::move(_Val));

++Iter;

then returns *this.
