Creates a new ScopedInstances.

Parameters:

domain - a non-null Domain

bq - a non-null Qualifiers

sq - a non-null Qualifiers

scopes - a non-null Scopes

considerActiveness - an AnnotationMirror used to signal that activeness should be taken into consideration during typesafe resolution; may be null

Throws:

NullPointerException - if any argument is null

proxiable

public boolean proxiable(Id id)

Returns true if and only if the supplied Id is proxiable.

Specified by:

proxiable in interface Instances

Parameters:

id - an Id; must not be null

Returns:

true if and only if the supplied Id is proxiable

Throws:

NullPointerException - if id is null

selectableOf

public final Selectable<Annotated<? extends AnnotatedConstruct>, Bean<?>> selectableOf(Selectable<? super Annotated<? extends AnnotatedConstruct>, Bean<?>> selectable)

Returns a Selectable<AnnotatedConstruct, Bean<?>> that properly considers the fact that a Scopelet may be active or inactive at any point for any reason.

Parameters:

selectable - a Selectable that will be used for all AnnotatedConstructs other than Scopelet types being sought for the purpose of instantiating or acquiring contextual instances; must not be null

Returns:

a non-null Selectable

Throws:

NullPointerException - if any argument is null

supplier

public final <I> Supplier<? extends I> supplier(Bean<I> bean,
 Creation<I> request)
