Disposing objects in CDI

Question

I was wondering if CDI had some way to dispose/close objects other than @Disposes methods?

For simple cases, I would like to do something like:

class MyObject {

    @Inject MyObject(MyDependencies...) {...}

    @Disposes void close() {...}
}

rather than having to create a @Disposes method elsewhere just to call close() like this:

class MyObjectManager {

    void closeMyObject(@Disposes MyObject myObject) {
        myObject.close();
    }
}

I think what you're looking for is @PreDestroy. This method gets called when whatever context the object is tied to is closed. Annotate a method with this and that method will be invoked whenever the object is meant to be destroyed.
