CleanupRegistry

AI-generated Key Takeaways

• CleanupRegistry manages resource cleanup by tracking objects and executing cleanup logic when they are garbage collected.

• It utilizes a ReferenceQueue to monitor garbage collection and a Runnable to perform cleanup tasks.

• CleanupRegistry allows registering objects for tracking and provides methods for manual resource release and reclaiming released resources.

• The register method associates a cleanup callback (Runnable) with an object, ensuring the callback is executed upon garbage collection.

public class CleanupRegistry
