Interface Summary

Interface	Description
ActiveDescriptor<T>	An ActiveDescriptor contains information about a Descriptor after it has been reified.
ClassAnalyzer	When HK2 automatically analyzes a class to find the constructor, fields, initializer methods and postConstruct and preDestroy methods it uses this service to analyze the class.
Context<T>	An implementation of this must be put into the system in order to create contextual instances of services.
Descriptor	A Descriptor is a bean-like structure that describes a service declaration in HK2.
DescriptorFileFinder	Implementations of this interface allow the customization of how hk2 inhabitant files are found
DynamicConfiguration	This class is used to add Descriptors to a ServiceLocator instance.
DynamicConfigurationService	The dynamic configuration service is the source of DynamicConfiguration instances, which can be used to bind and unbind entities into the system
ErrorInformation	This class has information in it about the error that has occurred
ErrorService	This interface should be implemented by those who wish to be notified of error conditions that occur within HK2.
Factory<T>	This interface should be implemented in order to provide a factory for another type.
FactoryDescriptors	This is a convenience class that links together the factory descriptor as a factory for another type and the factory as a service itself.
Filter	This object is used to search for items in the service registry
HK2Loader	This class is responsible for loading classes, and different implementations can be used for different descriptors.
IndexedFilter	This filter can be used to limit the set of Descriptors passed to the matches method.
Injectee	An Injectee represents the point of injection.
InjectionResolver<T>	This class allows users to provide a custom injection target for any annotation (including @Inject).
InstanceLifecycleEvent	This object contains information about a lifecycle event.
InstanceLifecycleListener	This processor is called for certain events in the lifecycle of instances of services.
IterableProvider<T>	This object can be injected rather than Provider or ExtendedProvider when it is desired to iterate over more than one returned instance of the type.
JustInTimeInjectionResolver	The JustInTimeInjectionResolver is called when an injection point cannot find anything to inject.
Populator	Implementations of this interface are used to populate HK2 service locators from inhabitants files
PopulatorPostProcessor	This interface allows the customization of services read in from an external source.
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.
ProxyCtl	Every proxy generated by HK2 will implement this interface, which can be used to have finer control on the behavior of the proxy
ServiceHandle<T>	This service handle can be used to get a specific instance of a service, and can be used to destroy that service as well
ServiceLocator	ServiceLocator is the registry for HK2 services
ServiceLocatorListener	This is added to ServiceLocatorFactory in order to listen on service locators coming and going.
SingleCache<T>	This cache can be used in some circumstances when there can be only one of a service.
ValidationInformation	This object contains information about the validation point.
ValidationService	This service can be used to add validation points to Descriptors.
Validator	This method is called when it determined that a type that is annotated with a Validating annotation is to be injected into any other class.

Class Summary

Class	Description
AnnotationLiteral<T extends java.lang.annotation.Annotation>	Supports inline instantiation of annotation type instances.
ServiceLocatorFactory	This factory can be used to create new named ServiceLocators
TypeLiteral<T>	Supports inline instantiation of objects that represent parameterized types with actual type parameters.

Enum Summary

Enum	Description
DescriptorType	This describes the type of descriptor
DescriptorVisibility	This enumeration determines how visibility of a descriptor
ErrorType	This enumeration describes the types of errors that might occur
InstanceLifecycleEventType	This describes the type of lifecycle events that can happen in the system
Operation	This defines the operations that may be validated
ServiceLocatorState	The possible states in which a service locator can be in.

Exception Summary

Exception	Description
HK2Exception	Base class for HK2 defined checked exceptions
HK2RuntimeException	Base class for HK2 defined runtime exceptions
MultiException	This exception can contain multiple other exceptions.
UnsatisfiedDependencyException	This exception will be found in a MultiException when a class has a dependency that should be satisfied but cannot be.

Annotation Types Summary

Annotation Type	Description
Metadata	This annotation marks a method of an annotation as providing a value that should be placed into the metadata of the descriptor.
PerLookup	PerLookup is the scope for objects that are created every time they are looked up.
PerThread	PerThread is a scope that operates like Singleton scope, except on a per-thread basis.
Proxiable	Scope annotations that are also marked with this annotation are proxiable.
Rank	This annotation is used to provide the initial rank of a service marked with Service.
Self	This annotation is placed on an injection point that is to be injected with the ActiveDescriptor that was used to create the instance.
Unproxiable	This annotation must go on a scope annotation in order to indicate that no services from this scope may be proxied.
Unqualified	An injection point can be annotated with @Unqualified if it should only be injected with services that have no qualifiers at all
UseProxy	This annotation is used when automatically analyzing a class or a {link Factory.provide() method to indicate that the descriptor either should or should not use a proxy.
Visibility	This annotation is used when automatically analyzing a class or a {link Factory.provide() method to indicate that the descriptor either should or should not have LOCAL visibility.
