Method Detail

create

public static <T> Creator<T> create(Class<T> c,
                                    Habitat habitat,
                                    MultiMap<String,String> metadata)

getAllInjectionResolvers

public static List<Inhabitant<? extends InjectionResolver>> getAllInjectionResolvers(Habitat habitat)

Returns all currently available injection annotations

Parameters:

habitat - the service registry

Returns:

the list of injection resolvers registered in this service registry in its parent.

qualifyingConstructors

public static <T> void qualifyingConstructors(Class<T> c,
                                              List<Constructor<?>> allList,
                                              Set<Class<? extends Annotation>> injectionAnnotations,
                                              Reference<Constructor<T>> defaultCtor,
                                              Reference<Constructor<T>> noArgCtor)

Returns all "eligible" constructors for injection. Eligibility is determined by: (a) the no-arg constructor, or (b) @Inject annotated constructor.

Note, however, that this does not verify that the arguments on the constructor are indeed injectable out of the habitat.

Parameters:

c - The class to find the constructors for

defaultCtor - (optional) The "favored" default constructor reference; meaning that all arguments can be injected based on the contents of the habitat

noArgCtor - (optional The no-arg constructor reference

isInjectable

public static boolean isInjectable(Set<Class<? extends Annotation>> injectionAnnotations,
                                   AnnotatedElement ae)
