Interface InterceptionMetadata

@Describe
public interface InterceptionMetadata

Provides a service descriptor, or an intercepted instance with information whether to, and how to intercept elements.

Used (mostly) by generated code (passed as a parameter to ServiceDescriptor.inject(io.helidon.service.registry.DependencyContext, InterceptionMetadata, java.util.Set, Object), and ServiceDescriptor.instantiate(io.helidon.service.registry.DependencyContext, InterceptionMetadata)).

Method Summary

Modifier and Type	Method	Description
<T> InterceptionInvoker<T>	createInvoker(ServiceInfo descriptor, Set<Qualifier> typeQualifiers, List<Annotation> typeAnnotations, TypedElementInfo element, InterceptionInvoker<T> targetInvoker, Set<Class<? extends Throwable>> checkedExceptions)	Create an invoker that handles interception if needed, for constructors.
<T> InterceptionInvoker<T>	createInvoker(Object serviceInstance, ServiceInfo descriptor, Set<Qualifier> typeQualifiers, List<Annotation> typeAnnotations, TypedElementInfo element, InterceptionInvoker<T> targetInvoker, Set<Class<? extends Throwable>> checkedExceptions)	Create an invoker that handles interception if needed.

Method Details

createInvoker

<T> InterceptionInvoker<T> createInvoker(ServiceInfo descriptor,
 Set<Qualifier> typeQualifiers,
 List<Annotation> typeAnnotations,
 TypedElementInfo element,
 InterceptionInvoker<T> targetInvoker,
 Set<Class<? extends Throwable>> checkedExceptions)

Create an invoker that handles interception if needed, for constructors.

Type Parameters:

T - type of the result of the invoker

Parameters:

descriptor - metadata of the service being intercepted

typeQualifiers - qualifiers on the type

typeAnnotations - annotations on the type

element - element being intercepted

targetInvoker - invoker of the element

checkedExceptions - expected checked exceptions that can be thrown by the invoker

Returns:

an invoker that handles interception if enabled and if there are matching interceptors, any checkedException will be re-thrown, any runtime exception will be re-thrown

createInvoker

<T> InterceptionInvoker<T> createInvoker(Object serviceInstance,
 ServiceInfo descriptor,
 Set<Qualifier> typeQualifiers,
 List<Annotation> typeAnnotations,
 TypedElementInfo element,
 InterceptionInvoker<T> targetInvoker,
 Set<Class<? extends Throwable>> checkedExceptions)

Create an invoker that handles interception if needed.

Type Parameters:

T - type of the result of the invoker

Parameters:

serviceInstance - instance of the service that is being intercepted

descriptor - metadata of the service being intercepted

typeQualifiers - qualifiers on the type

typeAnnotations - annotations on the type

element - element being intercepted

targetInvoker - invoker of the element

checkedExceptions - expected checked exceptions that can be thrown by the invoker

Returns:

an invoker that handles interception if enabled and if there are matching interceptors, any checkedException will be re-thrown, any runtime exception will be re-thrown
