Actually, there are some good reasons for most items being marked as
private in Zend_View_Abstract -- it's to prevent their usage directly
from the view scripts. It's a scoping issue.
The way Zend_View works, Zend_View::_run() actually performs an
include() on the view script, which means that it has full access to
$this. However, since _run() lives in Zend_View, and not
Zend_View_Abstract, that means that private properties and methods are
off limits, while protected and public ones remain accessible.
If you need to extend Zend_View, there are two ways to do so, and both
ar documented:
* Do so in a view script
* Implement Zend_View_Interface
