if语句中的返回在以下代码中做了什么？

public void startElement(String namespaceURI, String localName,String qName, 
                                         Attributes atts) throws SAXException
{
    depth++;
    if (localName.equals("channel"))
    {
        currentstate = 0;
        return;
    }
    if (localName.equals("image"))
    {
        // record our feed data - you temporarily stored it in the item :)
        _feed.setTitle(_item.getTitle());
        _feed.setPubDate(_item.getPubDate());
    }
    if (localName.equals("item"))
    {
        // create a new item
        _item = new RSSItem();
        return;
    }
    if (localName.equals("title"))
    {
        currentstate = RSS_TITLE;
        return;
    }
    if (localName.equals("description"))
    {
        currentstate = RSS_DESCRIPTION;
        return;
    }
    if (localName.equals("link"))
    {
        currentstate = RSS_LINK;
        return;
    } …
