Custom Type Traits vs Runtime Type Information
Developers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms meets developers should learn and use rtti when building applications that require dynamic polymorphism, such as in frameworks for serialization, reflection, or debugging tools where object types need to be determined at runtime. Here's our take.
Custom Type Traits
Developers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms
Custom Type Traits
Nice PickDevelopers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms
Pros
- +They are essential for tasks like type introspection, conditional compilation, and optimizing code paths based on type properties, such as checking if a type is integral, pointer, or has certain member functions
- +Related to: cplusplus-templates, template-metaprogramming
Cons
- -Specific tradeoffs depend on your use case
Runtime Type Information
Developers should learn and use RTTI when building applications that require dynamic polymorphism, such as in frameworks for serialization, reflection, or debugging tools where object types need to be determined at runtime
Pros
- +It is essential in scenarios involving heterogeneous collections, plugin architectures, or when implementing design patterns like Visitor or Factory, as it allows for safe type conversions and error handling without hardcoding type checks
- +Related to: object-oriented-programming, polymorphism
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Custom Type Traits if: You want they are essential for tasks like type introspection, conditional compilation, and optimizing code paths based on type properties, such as checking if a type is integral, pointer, or has certain member functions and can live with specific tradeoffs depend on your use case.
Use Runtime Type Information if: You prioritize it is essential in scenarios involving heterogeneous collections, plugin architectures, or when implementing design patterns like visitor or factory, as it allows for safe type conversions and error handling without hardcoding type checks over what Custom Type Traits offers.
