> Currently, Onami LifeCycle supports multiple post injection annotations that are 
> invoked after instantiated by Guice. It also supports a Dispose container that
> holds references to injected objects whereby annotated methods will be invoked
> in reverse injection order when the user calls a container method.
> I'd like to generalize both post injection and container to support
> more open-ended features. The features are being driven by functionality in Governator.
> For post injection, Governator supports ordering of annotations. i.e. @PreConfiguration 
> methods are invoked before @PostConstruct methods. For the life cycle container,
> Governator supports a @Warmup annotation and others. @Warmup methods are invoked by user
> direction after the Guice Injector has been created. 
> The change to post injection is straightforward. Instead of specifying a single post
> injection annotation, an ordered list of annotations is specified. The Guice
> injection listener is modified to iterate over the annotation list in order looking
> for matching methods.
> The change to the life cycle container is more involved. For clarity, the various classes
> and methods are renamed from "Dispose*" to "Stage*". The DefaultStager (formerly DefaultDisposer)
> takes a new argument that determines if objects are processed first-in-first-out or 
> first-in-last-out. The Stager interface is now parameterized with the Annotation
> that represents the "stage". The LifeCycleStageModule now binds with its parameterized
> annotation so that Stagers of each stage type can be injected. i.e.
> 	@Inject
> 	public Foo( Stager<Dispose> disposer )
> 	
> ...
> 	@Inject
> 	public Bar( Stager<Warmup> warmups )
> 	
> Obviously this is a very big change. My goal is to enhance Onami Lifecycle so that I
> can use it in Governator. I've enclosed the implementation as a zip file instead of a
> patch to make things easier to look at.
> I look forward to discussion/ideas on this!
