Access to Zend Framework classes

[tzyganu]

I understood from the Magento 2 presentations I attended so far that between the application and Zend Frameword (ZF) there is another layer, the Magento Framework (MF). This should make it easy to upgrade or change ZF if needed in the future.
This meas that everything found in app/code should not access ZF classes directly. The classes in there should refer only to classes from the MF.
But the method Magento\Cms\Controller\Adminhtml\Page\PostDataProcessor::filter uses an instance of Zend_Filter_Input.

public function filter($data)
{
    $inputFilter = new \Zend_Filter_Input(
        array('custom_theme_from' => $this->dateFilter, 'custom_theme_to' => $this->dateFilter),
        array(),
        $data
    );
    $data = $inputFilter->getUnescaped();
    return $data;
}

In case I understood this wrong and ZF access is allowed directly, please tell me and close this issue.

We didn't build an indirection layer on top of Zend Framework, with the exception of a few classes for specific needs -- such as DB adapter, for augmenting it with more features and possibility for DB abstraction layer.

This is a good idea and it was discussed by our team, but currently there are no plans to fix this. For now we'll submit your suggestion as a proposal...

@antonmakarenko Thanks for the info. I need to pay more attention during the presentations 😄 .
I will close this for now. There is no need for 'noise' issues in this list.
