C class template specialization
07 Jul 2025
Class template specialization is a technique that provides completely different class template implementations for specific types. Its core uses include: 1. Performance optimization, such as bypassing redundant logic for types such as int, char*; 2. Type adaptation, and handling type logic with large differences; 3. Compatibility processing, such as distinguishing pointer and reference types. Fully specialization specifies all parameter types, while partial specialization specifies only some parameters or constraints, and is only applicable to class templates. Note when writing: specialized class bodies must be fully defined, avoid repeated definitions, and prioritize matching of the most specific version.
