Subject: What is meant by << operator ???

What is meant by << operator?

For example this operator is used in following code,


/*****************************************************/
def add_product(product)
  current_item = @items.find {|item| item.product == product}
  if current_item
    current_item.increment_quantity
  else
    current_item = CartItem.new(product)
  @items << current_item
  end
  current_item
end
/*****************************************************/
