MulleObjCRuntimeObject

The MulleObjCRuntimeObject protocol defines the core runtime functionality for objects in mulle-objc. This is the base protocol that all objects must implement.

Required Methods

Object Information

• -class - Get object’s class
• -methodForSelector: - Get method implementation

Message Sending

• -performSelector: - Perform selector
• -performSelector:withObject: - With one argument
• -performSelector:withObject:withObject: - With two arguments

Protocol Support

• -conformsToProtocol: - Check protocol conformance
• -respondsToSelector: - Check method availability

Thread Safety

• -mulleIsThreadSafe - Check thread safety
• -mulleIsAccessible - Check accessibility

Helper Functions

• MulleObjCObjectGetClass - Get object’s class
• MulleObjCObjectGetMethodForSelector - Get method implementation
• MulleObjCObjectConformsTo - Check protocol conformance

Important Notes

1. Core Protocol
   • Base functionality
   • Required methods
   • Runtime support
   • Thread safety
2. Thread Safety
   • Check thread affinity
   • Handle concurrent access
   • Use proper locks
   • Consider TAO rules
3. Best Practices
   • Validate objects
   • Handle nil cases
   • Document usage
   • Test thoroughly
4. Performance
   • Cache lookups
   • Minimize locks
   • Consider inlining
   • Handle contention

Note: This protocol provides the minimal runtime functionality required for all objects in mulle-objc. It is typically implemented by root classes like NSObject.
