Class Request<I,R>

java.lang.Object

org.microbean.reference.Request<I,R>

Type Parameters:

I - the contextual instance type (see for example Creation)

R - the contextual reference type (see References)

All Implemented Interfaces:

AutoCloseable, Iterable<R>, Creation<I>, Destruction, References<R>, ReferencesSelector

public class Request<I,R>
extends Object
implements Creation<I>, Destruction, References<R>

A central object representing a request for dependencies that is a Creation (and therefore also a Destruction) and a References.

Instances of this class are the heart and soul of a dependency injection and acquisition system.

Request

public Request(Domain domain,
 Selectable<? super AttributedType,Bean<?>> s,
 Instances instances,
 AutoCloseableRegistry acr,
 ClientProxier cp,
 BeanReduction<I> br)

Creates a new Request.

Parameters:

domain - a Domain; must not be null

s - a Selectable providing access to Beans by AttributedType; must not be null

instances - an Instances responsible for using a Bean to acquire an appropriate Supplier of contextual instances; must not be null

acr - an AutoCloseableRegistry; may be null in which case a default implementation will be used instead

cp - a ClientProxier; must not be null

br - a BeanReduction describing the request in progress; may be null in certain rare primordial cases

Throws:

NullPointerException - if domain, s, instances, or cp is null
