title: meaning of "return this"
body: <p>I have been following android tutorial on the internet about SQLite. I got a statement which I'm not sure about: </p>
  
  <pre><code>public HotOrNot open(){
      ourHelper = new DbHelper(ourContext);
      ourDatabase = ourHelper.getWritableDatabase();
      return this;  
  }
  </code></pre>
  
  <p>What does <code>return this</code> mean in this method ? is it the current object or context ? thanks</p>
