Description

Interface Summary

ContextualFactory<T>	Extension to the simple Factory that supports contextual injection.
Creator<T>	Encapsulates how to create an object.
Enableable	Contract used for enabling/disabling a service, and querying whether it is currently enabled.
Factory<T>	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	Contract responsible for habitat creation.
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.
InhabitantProviderInterceptor	A hook for providers to implement in order to extend or redefine the inhabitant Hk2 will incorporate into the Habitat.
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.
InjectionPoint	Used to describe the injection point and context of the injection.
PostConstruct	Compatibility class for PostConstruct
PreDestroy	Compatibility class for the PreDestroy interface
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.
SimpleServiceLocator	Provide a simple abstraction for getting services by contract or type.

Class Summary

AbstractRunLevelService<T>	A default implementation for the RunLevelService that component provides can derive from to provide their own component-related lifecycle.
AsyncWaiter	Helper class that will manage all AsyncPostConstruct services and Futures for completion.
Constants	Common metadata properties used by the inhabitant / habitat.
ContractLocatorImpl<T>	Implementation of the ContractLocator interface.
Creators	Creator factory.
DescriptorImpl	A simple Descriptor.
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.
HK2ProviderImpl	Default Hk2 Provider based on the habitat.
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.
InjectionManager.InjectContext
MultiMap<K,V>	Map from a key to multiple values.
MultiThreadedInhabitantActivator	A simple multi-threaded based InhabitantActivator
PerLookup	Compatibility class for PerLookup scope
Reference<T>	A Simple Reference holder.
Scope
Singleton	Compatibility class for the Singleton scope.

Enum Summary

HabitatListener.EventType
InhabitantListener.EventType

Exception Summary

ComponentException	Exception thrown when a component's dependency is not satisfied at the time the component is expected to be put in commission.
RunLevelException	Exception related to the operations of the RunLevelService.
UnsatisfiedDependencyException	Exception thrown by the injection manager when a dependency is not satisfied when performing injection.
