Abyss-lord opened a new pull request, #6881: URL: https://github.com/apache/gravitino/pull/6881
### What changes were proposed in this pull request? Refactor EventBus#dispatchEvent. By adding the `accept(EventVisitor visitor)` method to BaseEvent and its subclasses, the handling logic is delegated to the event itself. This allows the EventBus to simply call `event.accept(InternalVisitor())`, with the event determining how it should be processed. 1. **Type-safe** – Eliminates the need for `instanceof` checks 2. **Clear decoupling** – Events are only responsible for invoking `accept` method, without knowing the listener implementation 3. **Strong encapsulation** – Prevents external misuse by restricting direct access to visitor methods 4. **Easily extensible** – Adding new event types only requires creating new classes and visitXxx() methods, without modifying the dispatch logic ### Why are the changes needed? Fix: #6880 ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? local test. -- This is an automated message from the Apache Git Service.
