magento-plugins-interceptors

Magento 2 plugins (interceptors) modify class behavior without inheritance by using before, after, and around methods to intercept public calls and change arguments or return values via Dependency Injection.

Before plugins change method arguments before execution, after plugins modify return values after execution, and around plugins wrap the entire method execution to control the original method call flow and add custom logic.

Create a beforeSave plugin for the Magento\Catalog\Model\Product class to intercept the save method and inject your custom validation logic without rewriting the core model.

Yes, declaring Magento 2 plugins requires XML configuration within the Dependency Injection system to specify the target class and the plugin class implementing the interception logic.

Yes, Magento 2 plugins can intercept public methods on third-party module classes, allowing you to modify their behavior and extend functionality without altering the original extension code or using inheritance.

Magento 2 plugins only intercept public methods and require understanding of the Dependency Injection system and XML configuration, making them unsuitable for modifying private methods or non-public class members.
