Interface Classes vs Pimpl Idiom
Developers should learn and use interface classes when designing systems that require clear separation of concerns, such as in large-scale applications, APIs, or frameworks where multiple implementations might exist meets developers should use the pimpl idiom when building c++ libraries or large-scale applications to minimize recompilation times when implementation details change, as it breaks compile-time dependencies. Here's our take.
Interface Classes
Developers should learn and use interface classes when designing systems that require clear separation of concerns, such as in large-scale applications, APIs, or frameworks where multiple implementations might exist
Interface Classes
Nice PickDevelopers should learn and use interface classes when designing systems that require clear separation of concerns, such as in large-scale applications, APIs, or frameworks where multiple implementations might exist
Pros
- +They are essential for implementing design patterns like Strategy, Factory, or Adapter, and for writing unit tests with mock objects
- +Related to: object-oriented-programming, polymorphism
Cons
- -Specific tradeoffs depend on your use case
Pimpl Idiom
Developers should use the Pimpl Idiom when building C++ libraries or large-scale applications to minimize recompilation times when implementation details change, as it breaks compile-time dependencies
Pros
- +It's particularly useful for creating stable APIs, reducing header file bloat, and isolating platform-specific code, making it easier to maintain and evolve software over time
- +Related to: c-plus-plus, object-oriented-programming
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Interface Classes if: You want they are essential for implementing design patterns like strategy, factory, or adapter, and for writing unit tests with mock objects and can live with specific tradeoffs depend on your use case.
Use Pimpl Idiom if: You prioritize it's particularly useful for creating stable apis, reducing header file bloat, and isolating platform-specific code, making it easier to maintain and evolve software over time over what Interface Classes offers.
