Interface InvocationEventEmitter

All Known Implementing Classes:
NoOpInvocationEventEmitter, Slf4jInvocationEventEmitter
public interface InvocationEventEmitter
Output port responsible for delivering a MethodInvocationEvent to wherever it needs to go: an SLF4J logger, a metrics backend, a message queue, or any other sink.

This interface belongs to the framework-free core module and has no knowledge of how events are actually published. Adapter modules (for example logged-spring) provide the real implementation. A no-op implementation is provided in this module so that the core can be used standalone, without any adapter, without throwing an exception.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    emit(MethodInvocationEvent event)
    Publishes the given invocation event to whatever sink this implementation targets.

  • Method Details

    • emit

      void emit(MethodInvocationEvent event)
      Publishes the given invocation event to whatever sink this implementation targets.

      Implementations must not throw checked or unchecked exceptions that would propagate back into the intercepted method call. Emission failures (for example a logging backend being unavailable) should be handled internally by the implementation.

      Parameters:
      event - the invocation event to publish, never null
