* Joomla! Cache view type object

* Get the cached view data
* @param object $view The view object to cache output for
* @param string $method The method name of the view method to cache output for
* @param string $group The cache data group
* @param string $id The cache data id
* @return boolean True if the cache is hit (false else)

* No hit so we have to execute the view
// Capture and echo output
* For a view we have a special case. We need to cache not only the output from the view, but the state
* of the document head after the view has been rendered. This will allow us to properly cache any attached
* scripts or stylesheets or links or any other modifications that the view has made to the document object
$cached['head'] =
$document->getHeadData();
* Generate a view cache id
* @param object $view The view object to cache output for
* @param string $method The method name to cache for the view object
* @return string MD5 Hash : view cache id
