fl::IdTracker Class Reference

Detailed Description

Thread-safe ID tracker that maps void* pointers to unique integer IDs.

Features:

• Auto-incrementing ID counter for new entries
• Thread-safe operations with mutex protection
• Instantiable class - create as many trackers as needed
• Support for removal of tracked pointers

Usage: IdTracker tracker; // Create instance int id = tracker.getOrCreateId(ptr); bool found = tracker.getId(ptr, &id); tracker.removeId(ptr);

For singleton behavior, wrap in your own singleton: static IdTracker& getGlobalTracker() { static IdTracker instance; return instance; }
