It is not good way to override core class of Magento. But I have to do this because I am in way that class is abstract and method is protected so I think preference and pluginshould not work. I found couple of answers about Override abstract class in Magento 2 and this one but both are not useful for me. So is there any other way to achieve this ? I want to override this class

\Magento\Sales\Model\Order\Pdf\AbstractPdf

Thanks

What i did

di.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Sales\Model\Order\Pdf\Items\Invoice\DefaultInvoice" type="Mycompany\Tax\Model\Order\Pdf\Items\Invoice\DefaultInvoice" />
    <preference for="Magento\Sales\Model\Order\Pdf\Invoice" type="Mycompany\Tax\Model\Order\Pdf\Invoice" />

and I copied the functions that i wanted to override of the abstract class in app\code\Mycomany\Tax\Model\Order\Pdf\Invoice.php like one thing i wanted to change was fonts

 /**
     * Set font as regular
     *
     * @param  \Zend_Pdf_Page $object
     * @param  int $size
     * @return \Zend_Pdf_Resource_Font
     */
    protected function _setFontRegular($object, $size = 7)
    {
        $font = \Zend_Pdf_Font::fontWithPath(
            $this->getFontsDir() . ('dejavu-sans/DejaVuSansCondensed.ttf')
        );
        $object->setFont($font, $size);
        return $font;
    }
    /**
     * Set font as bold
     *
     * @param  \Zend_Pdf_Page $object
     * @param  int $size
     * @return \Zend_Pdf_Resource_Font
     */
    protected function _setFontBold($object, $size = 6)
    {
        $font = \Zend_Pdf_Font::fontWithPath(
            $this->getFontsDir() . ('dejavu-sans/DejaVuSansCondensed-Bold.ttf')
        );
        $object->setFont($font, $size);
        return $font;
    }

    /**
     * Set font as italic
     *
     * @param  \Zend_Pdf_Page $object
     * @param  int $size
     * @return \Zend_Pdf_Resource_Font
     */
    protected function _setFontItalic($object, $size = 7)
    {
        $font = \Zend_Pdf_Font::fontWithPath(
            $this->getFontsDir() . ('dejavu-sans/DejaVuSans-Oblique.ttf')
        );
        $object->setFont($font, $size);
        return $font;
    }

This is how i modified my Insertorder

My approach was override the class that is using that method rather than abstract class

  • Thanks Vishwas for the some hints, but I think it is not useful to me actually I want to do some work on protected function insertOrder() , but still +1 from me for your efforts – Keyur Shah Jan 12 '17 at 10:31
  • @KeyurShah i have modified insertOrder() as well added , added in my answer hope it helps – Vishwas Bhatnagar Jan 12 '17 at 10:37
