CleanupRegistry

  • 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.
