Nested Classes

Modifier and Type	Class	Description
static final class	Model.DependencyResolution	A representation of the attempted resolution of a dependency, represented by an Annotated<? extends AnnotatedConstruct>, to a List of Beans that match it.

Method Summary

Modifier and Type	Method	Description
final Set<Model.DependencyResolution>	ambiguousDependencyResolutions()	Returns a non-null, immutable, determinate Set of all Model.DependencyResolutions managed by this Model that are ambiguous.

static Model	of(Selectable<? super Annotated<? extends AnnotatedConstruct>, ? extends Bean<?>> s)	Returns a non-null Model built from the supplied Selectable.
final BiFunction<? super Annotated<? extends AnnotatedConstruct>, Function<? super Annotated<? extends AnnotatedConstruct>, ? extends List<Bean<?>>>, ? extends List<Bean<?>>>	toSelectionCache()	Returns a non-null BiFunction that represents a compute-if-absent operation on an internal, unbounded, thread-safe cache.
final Set<Model.DependencyResolution>	unsatisfiedDependencyResolutions()	Returns a non-null, immutable, determinate Set of all Model.DependencyResolutions managed by this Model that are unsatisfied.

Method Details

equals

public final boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

valid

public final boolean valid()

Returns true if and only if this Model is valid.

A Model is valid if and only if, for each of its Model.DependencyResolutions, there exists exactly one Bean.

Returns:

true if and only if this Model is valid

ambiguousDependencyResolutions

public final Set<Model.DependencyResolution> ambiguousDependencyResolutions()

Returns a non-null, immutable, determinate Set of all Model.DependencyResolutions managed by this Model that are ambiguous.

Returns:

a non-null, immutable, determinate Set of all Model.DependencyResolutions managed by this Model that are ambiguous

See Also:

• Model.DependencyResolution.ambiguous()

unsatisfiedDependencyResolutions

public final Set<Model.DependencyResolution> unsatisfiedDependencyResolutions()

Returns a non-null, immutable, determinate Set of all Model.DependencyResolutions managed by this Model that are unsatisfied.

Returns:

a non-null, immutable, determinate Set of all Model.DependencyResolutions managed by this Model that are unsatisfied

See Also:

• Model.DependencyResolution.unsatisfied()

toSelectionCache

public final BiFunction<? super Annotated<? extends AnnotatedConstruct>, Function<? super Annotated<? extends AnnotatedConstruct>, ? extends List<Bean<?>>>, ? extends List<Bean<?>>> toSelectionCache()

Returns a non-null BiFunction that represents a compute-if-absent operation on an internal, unbounded, thread-safe cache.

The return value is suitable for passing to the Selectables.caching(Selectable, BiFunction) method.

Returns:

a non-null BiFunction that represents a compute-if-absent operation on an internal, unbounded, thread-safe cache

Throws:

IllegalStateException - if this Model is not valid

of

public static Model of(Selectable<? super Annotated<? extends AnnotatedConstruct>, ? extends Bean<?>> s)

Returns a non-null Model built from the supplied Selectable.

Parameters:

s - a non-null Selectable

Returns:

a non-null Model built from the supplied Selectable

Throws:

NullPointerException - if s is null
