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

Interface Classes

Nice Pick

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

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.

The Bottom Line
Interface Classes wins

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
