Is Something-Aware a design pattern?

Question

In Struts2 interceptor package, we can see many XXXAware interface, like ApplicationAware, CookieAware, and so on.

In Spring framework, ApplicationContextAware and BeanFactoryAware... can be seen as well.

I also follow this design concept to implement my framework. Is this a kind of design pattern? Does it have a name?

Answer 1

The design pattern is still Dependency Injection and IOC. The marker interfaces are just a clunky language-version specific way of implementing it.

Answer 2

It sounds like maybe it's using the Observer pattern.
