Interface DependencyInjector

All Superinterfaces:

AutoCloseable, SafeCloseable

All Known Implementing Classes:

SpringDependencyInjector

@UnstableApi
public interface DependencyInjector
extends SafeCloseable

Injects dependencies that are specified in RequestConverter.value(), ResponseConverter.value(), ExceptionHandler.value(), Decorator.value() and DecoratorFactory.value(). If the dependencies are not injected by this DependencyInjector, they are created via the default constructor, which does not have a parameter, of the classes.

Method Summary

Modifier and Type	Method	Description
<T> T	getInstance(Class<T> type)	Returns the instance of the specified Class.
static DependencyInjector	ofSingletons(Iterable<Object> singletons)	Returns a DependencyInjector that injects dependencies using the specified singleton instances.
static DependencyInjector	ofSingletons(Object... singletons)	Returns a DependencyInjector that injects dependencies using the specified singleton instances.
default DependencyInjector	orElse(DependencyInjector dependencyInjector)	Returns a new DependencyInjector that tries getInstance(Class) of this DependencyInjector first and the specified DependencyInjector.

Method Details

ofSingletons

static DependencyInjector ofSingletons(Object... singletons)

Returns a DependencyInjector that injects dependencies using the specified singleton instances. The instances are closed if it implements AutoCloseable when the Server stops.

ofSingletons

static DependencyInjector ofSingletons(Iterable<Object> singletons)

Returns a DependencyInjector that injects dependencies using the specified singleton instances. The instances are closed if it implements AutoCloseable when the Server stops.

getInstance

@Nullable
<T> T getInstance(Class<T> type)

Returns the instance of the specified Class.

orElse

default DependencyInjector orElse(DependencyInjector dependencyInjector)

Returns a new DependencyInjector that tries getInstance(Class) of this DependencyInjector first and the specified DependencyInjector.
