DefaultMethodInterceptor class final

Default implementation of MethodInterceptorRegistry and related intercept processing.

This class serves as the central registry and dispatcher for method-level interceptors in a JetLeaf application. It is responsible for:

1. Collecting all MethodInterceptor implementations from the PodFactory.
2. Applying ordering rules based on PriorityOrdered and Ordered annotations.
3. Managing a custom MethodInterceptorDispatcher if provided.
4. Injecting itself into any Interceptable pods so they can delegate method calls for interception.

Responsibilities

• Interceptor Management: Add, remove, and maintain ordered sets of interceptors.
• Dispatcher Configuration: Support custom dispatcher injection and fallback to default dispatching logic.
• Pod Lifecycle Integration: Implements PodInstantiationProcessor and SmartInitializingSingleton to hook into pod creation and initialization events for automatic registration of interceptors.
• Logging: Uses JetLeaf logging for info/debug during interceptor collection and registration.

Lifecycle

1. During pod instantiation, this registry can attach itself to Interceptable pods.
2. After singleton initialization (onSingletonReady), it:
   • Collects all MethodInterceptor pods from the PodFactory.
   • Collects all MethodInterceptorConfigurer pods and invokes their configure method to register additional interceptors.
3. Interceptors are sorted by priority and order annotations using AnnotationAwareOrderComparator.
4. Once initialized, the registry can be used to intercept method calls transparently via AbstractMethodDispatcher.

Example Usage

final registry = DefaultMethodInterceptor();
registry.setPodFactory(podFactory);
await registry.onSingletonReady(); // Collect interceptors

// Adding a custom interceptor manually
registry.addMethodInterceptor(CustomLoggingInterceptor());

// Setting a custom dispatcher if needed
registry.setMethodInterceptorDispatcher(MyCustomDispatcher());
