-<p>The Output class is a core class with one main function: To send the

-<p>Under normal circumstances you won&#8217;t even notice the Output class since
-it works transparently without your intervention. For example, when you
-use the <a class="reference internal" href="loader.html"><em>Loader</em></a> class to load a view file,
-it&#8217;s automatically passed to the Output class, which will be called
-automatically by CodeIgniter at the end of system execution. It is

-need to.</p>
