Direct Method Calls vs Message Forwarding
Developers should use direct method calls when they need simple, efficient, and predictable execution paths, such as in performance-critical applications or when working with well-defined APIs where the method to call is known at compile-time meets developers should learn message forwarding when working with dynamic languages like objective-c or swift to implement advanced patterns like proxy objects, where one object stands in for another to control access or add functionality. Here's our take.
Direct Method Calls
Developers should use direct method calls when they need simple, efficient, and predictable execution paths, such as in performance-critical applications or when working with well-defined APIs where the method to call is known at compile-time
Direct Method Calls
Nice PickDevelopers should use direct method calls when they need simple, efficient, and predictable execution paths, such as in performance-critical applications or when working with well-defined APIs where the method to call is known at compile-time
Pros
- +This is common in scenarios like utility functions, mathematical operations, or when implementing design patterns like the Template Method, where base class methods are directly invoked by derived classes
- +Related to: object-oriented-programming, function-calls
Cons
- -Specific tradeoffs depend on your use case
Message Forwarding
Developers should learn message forwarding when working with dynamic languages like Objective-C or Swift to implement advanced patterns like proxy objects, where one object stands in for another to control access or add functionality
Pros
- +It's essential for building flexible architectures, such as in iOS/macOS development for handling unimplemented methods dynamically, enabling features like method interception or creating adaptable components that can respond to unknown messages at runtime
- +Related to: objective-c, swift
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Direct Method Calls if: You want this is common in scenarios like utility functions, mathematical operations, or when implementing design patterns like the template method, where base class methods are directly invoked by derived classes and can live with specific tradeoffs depend on your use case.
Use Message Forwarding if: You prioritize it's essential for building flexible architectures, such as in ios/macos development for handling unimplemented methods dynamically, enabling features like method interception or creating adaptable components that can respond to unknown messages at runtime over what Direct Method Calls offers.
Developers should use direct method calls when they need simple, efficient, and predictable execution paths, such as in performance-critical applications or when working with well-defined APIs where the method to call is known at compile-time
