Interface Summary

CageBuilder<T>	Deprecated. this is scheduled for removal
Creator<T>	Encapsulates how to create an object.
Enableable	Contract used for enabling/disabling a service, and querying whether it is currently enabled.
Factory	Hook to create/obtain an instance of a component from somewhere, instead of letting the auto-depends create it via the constructor.
Habitat.NotifyCall
HabitatFactory
HabitatListener	For Listening to the Habitat.
Inhabitant<T>	Represents a component in the world of Habitat.
InhabitantActivator	Contract for handling the activation and releasing of an inhabitant.
InhabitantFilter	Contract used to determine if an inhabitant matches some criteria determined by the implementation.
InhabitantListener	For Listening to an Inhabitant.
InhabitantRequested	Services implementation may require access to the inhabitant object wrapping them.
InhabitantSorter	Contract for sorting inhabitants.
InhabitantsParserFactory
InhabitantTracker	Tracks an inhabitant, or set of inhabitants.
InhabitantTracker.Callback	The callback is called when there is an event changing one of the tracked inhabitants.
InhabitantTrackerContext	The filter that is passed to the InhabitantTracker creation.
Injectable	A resource that can be injected into a component might optionally want to be notified of such injection.
PostConstruct	Classes implementing this interface register an interest in being notified when the instance has been created and the component is about to be place into commission.
PreDestroy	Components implementing this interface registers an interest in being notified when they are about to be decommissioned.
RunLevelListener	Implementations of RunLevelService are encouraged to use this contract for publishing RunLevel events.
RunLevelService<T>	Implementations of this contract are responsible for orchestration lifecycle events (i.e., start levels) in Hk2.
RunLevelState<T>	Holds the state(s) for a particular RunLevelService.
ServiceContext	Information about a service.

Class Summary

CageBuilder.Registerer<T>	When CageBuilder enters habitat, look for existing inhabitants that were supposed to be caged by this and cage them all.
Constants	Common metadata properties used by the inhabitant / habitat.
Creators	Creator factory.
Habitat	A set of templates that constitute a world of objects.
HabitatListenerWeakProxy	A proxy where the underlying HabitatListener is held as a weak proxy and is automatically removed from the habitat if the proxy is GC'ed.
Inhabitants	Deprecated. Use Inhabitants instead.
InhabitantTrackerContextBuilder	Builder for constructing InhabitantTrackerContext types.
InhabitantTrackerContextBuilder.AlteredLdapMatcherFilter
InhabitantTrackerContextImpl	Default implementation of InhabitantTrackerContext.
InjectionManager	InjectionManager is responsible for injecting resources into a component.
MultiMap<K,V>	Map from a key to multiple values.

Scope
Singleton	Singleton scope.
