In the field of software development, an interceptor pattern is a software design pattern that is used when software systems or frameworks want to offer a way to change, or augment, their usual processing cycle. Key aspects of the pattern are that the change is transparent and used automatically. In essence, the rest of the system does not have to know something has been added or changed and can keep working as before. To facilitate this, a predefined interface for extension has to be implemented, some kind of dispatching mechanism is required where interceptors are registered (this may be dynamic, at runtime, or static, e.g. through configuration files) and context objects are provided, which allow access to the framework’s internal state.
