Magento2 : Overriding Model file not working

Question

I want to override Magento\Payment\Model\Info::setAdditionalInformation() function my code is as below

<preference for="Magento\Payment\Model\Info" type="Xxx\Yyy\Model\Payment\Info" />

and file is app\code\Xxx\Yyy\Model\Payment\Info.php

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Xxx\Yyy\Model\Payment;

/**
 * Payment information model
 *
 * @api
 * @since 100.0.2
 */
class Info extends \Magento\Payment\Model\Info
{
    /**
     * Additional information container
     *
     * @var array
     */
    protected $_additionalInformation = [];

/**
 * @param \Magento\Framework\Model\Context $context
 * @param array $data
 */
public function __construct(
    \Magento\Framework\Model\Context $context,
    \Magento\Framework\Registry $registry,
    \Magento\Framework\Api\ExtensionAttributesFactory $extensionFactory,
    \Magento\Framework\Api\AttributeValueFactory $customAttributeFactory,
    \Magento\Payment\Helper\Data $paymentData,
    \Magento\Framework\Encryption\EncryptorInterface $encryptor,
    \Magento\Framework\Model\ResourceModel\AbstractResource $resource = null,
    \Magento\Framework\Data\Collection\AbstractDb $resourceCollection = null,
    array $data = []
) {
    parent::__construct(
        $context,
        $registry,
        $extensionFactory,
        $customAttributeFactory,
        $paymentData,
        $encryptor,
        $resource,
        $$resourceCollection,
        $data
    );
}

public function setAdditionalInformation($key, $value = null)
{
    if (is_object($value)) {
        throw new \Magento\Framework\Exception\LocalizedException(__('The payment disallows storing object XXXXXXXXXXXX'));
    }

    $this->_initAdditionalInformation();
    if (is_array($key) && $value === null) {
        $this->_additionalInformation = $key;
    } else {
        $this->_additionalInformation[$key] = $value;
    }
    return $this->setData('additional_information', $this->_additionalInformation);
}

}

When I compiled not getting any error,but unfortunately I cant override this function.

EDIT
my di.xml file code

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

Answer 1

In your modules di.xml file you will have to declare the tag preference to override a file:

<preference for="Magento\Payment\Model\Info" type="Xxx\Yyy\Model\Payment\Info" />

You can override the file depending on the area or for both areas i.e adminhtml and frontend.

Answer 2

please try replacing your constructor with below code:

public function __construct(
\Magento\Framework\Model\Context $context,
\Magento\Framework\Registry $registry,
\Magento\Framework\Api\ExtensionAttributesFactory $extensionFactory,
\Magento\Framework\Api\AttributeValueFactory $customAttributeFactory,
\Magento\Payment\Helper\Data $paymentData,
\Magento\Framework\Encryption\EncryptorInterface $encryptor,
\Magento\Framework\Model\ResourceModel\AbstractResource $resource = null,
\Magento\Framework\Data\Collection\AbstractDb $resourceCollection = null,
array $data = []
) {
parent::__construct(
    $context,
    $registry,
    $extensionFactory,
    $customAttributeFactory,
    $paymentData,
    $encryptor
);

}

IF it not work please let me know which error are you facing?
