Override _prepareSpecificInformation method of \Magento\Payment\Block\Info\Cc class - magento2

Question

I want to override _prepareSpecificInformation method of the Magento\Payment\Block\Info\Cc class
This is Core class.
vendor/magento/module-payment/Block/Info/Cc.php
<?php
namespace Magento\Payment\Block\Info;
/**
* Credit card generic payment info
*
* #api
* #since 100.0.2
*/
class Cc extends \Magento\Payment\Block\Info
{
protected function _prepareSpecificInformation($transport = null)
{
if (null !== $this->_paymentSpecificInformation) {
return $this->_paymentSpecificInformation;
}
$transport = parent::_prepareSpecificInformation($transport);
$data = [];
if ($ccType = $this->getCcTypeName()) {
$data[(string)__('Credit Card Type')] = $ccType;
}
if ($this->getInfo()->getCcLast4()) {
$data[(string)__('Credit Card Number')] = sprintf('xxxx-%s', $this->getInfo()->getCcLast4());
}
if (!$this->getIsSecureMode()) {
if ($ccSsIssue = $this->getInfo()->getCcSsIssue()) {
$data[(string)__('Switch/Solo/Maestro Issue Number')] = $ccSsIssue;
}
$year = $this->getInfo()->getCcSsStartYear();
$month = $this->getInfo()->getCcSsStartMonth();
if ($year && $month) {
$data[(string)__('Switch/Solo/Maestro Start Date')] = $this->_formatCardDate($year, $month);
}
}
return $transport->setData(array_merge($data, $transport->getData()));
}
Following is what I have done.
Muk/OrderEmail/etc/di.xml
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Payment\Block\Info\Cc" type="Muk\OrderEmail\Block\Info\Cc"/>
</config>
My custom class
app/code/Muk/OrderEmail/Block/Info/Cc.php
<?php
declare(strict_types=1);
namespace Muk\OrderEmail\Block\Info;
use Magento\Framework\DataObject;
use Magento\Framework\Exception\LocalizedException;
class Cc extends \Magento\Payment\Block\Info\Cc
{
public function __construct
(
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Payment\Model\Config $paymentConfig,
array $data = [])
{
parent::__construct($context, $paymentConfig, $data);
}
/**
* Prepare credit card related payment info
*
* #param DataObject|array $transport
* #return DataObject
* #throws LocalizedException
*/
protected function _prepareSpecificInformation($transport = null)
{
if (null !== $this->_paymentSpecificInformation) {
return $this->_paymentSpecificInformation;
}
$transport = parent::_prepareSpecificInformation($transport);
$data = [];
if ($ccType = $this->getCcTypeName()) {
$data[(string)__('Credit Card Type')] = $ccType;
}
if ($this->getInfo()->getCcLast4()) {
$data[(string)__('Credit Card Number')] = sprintf('xxxx-%s', $this->getInfo()->getCcLast4());
}
// Custom information
if ($ccType = $this->getCcTypeName()) {
$data[(string)__('Name on the Card:')] = $this->getInfo()->getCcOwner();
}
// End Custom information
if (!$this->getIsSecureMode()) {
if ($ccSsIssue = $this->getInfo()->getCcSsIssue()) {
$data[(string)__('Switch/Solo/Maestro Issue Number')] = $ccSsIssue;
}
$year = $this->getInfo()->getCcSsStartYear();
$month = $this->getInfo()->getCcSsStartMonth();
if ($year && $month) {
$data[(string)__('Switch/Solo/Maestro Start Date')] = $this->_formatCardDate($year, $month);
}
}
return $transport->setData(array_merge($data, $transport->getData()));
}
}
module.xml
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Muk_OrderEmail">
<sequence>
<module name="Magento_Payment"/>
<module name="Magento_Backend"/>
<module name="Magento_Sales"/>
<module name="Magento_Quote"/>
<module name="Magento_Checkout"/>
</sequence>
</module>
</config>
registration.php
<?php
declare(strict_types=1);
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Muk_OrderEmail',
__DIR__
);
But this override is not working for me.

Answer 1

It turned out that I was overriding a wrong file. Because the \Magento\Payment\Block\Info\Cc was already overridden by a custom module.
After correcting the preference it worked for me.
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="VendorName\Paymetric\Block\Xiintercept\Info\Iframe" type="Muk\OrderEmail\Block\Info\Cc"/>
</config>

After investigating in this, we have found solution for this. You can not override _prepareSpecificInformation method directly because this method is overided into another class that name is Magento\Paypal\Block\Payment\Info.
You have to override this class into custom module than you can do whatever changes into function that you want do.
