JSON Config Writer Input Refactoring Summary

Overview

Converted free functions in json_config_writer_input.cpp to class methods of JsonConfigWriterService.

Files Modified

1. json_config_writer_input.cpp

Changes:

• Changed include from json_config_writer_internal.hpp to json_config_writer_service.hpp
• Changed namespace from sdl3cpp::services::impl::json_config_writer to sdl3cpp::services::impl
• Removed anonymous namespace
• Converted addMappingObject() from free function to JsonConfigWriterService::addMappingObject()
• Converted buildInputSection() from free function to JsonConfigWriterService::buildInputSection()
• Updated call sites to use this->addMappingObject() instead of addMappingObject()

Functions Converted:

1. addMappingObject() - Previously in anonymous namespace
2. buildInputSection() - Previously in namespace scope

2. json_config_writer_service.hpp

Changes:

• Added includes: <string>, <unordered_map>
• Added forward declarations for rapidjson types (for faster compilation)
• Added private method declarations:
  • void addMappingObject(...)
  • void buildInputSection(...)

3. json_config_writer_service.cpp

Changes:

• Removed include of json_config_writer_internal.hpp
• Updated call sites to use this->buildInputSection() instead of json_config_writer::buildInputSection()

4. json_config_writer_internal.hpp

Changes:

• Removed declaration of buildInputSection() (now a class method)

Benefits

1. Better encapsulation: Functions are now properly scoped within the class
2. Clearer ownership: Methods explicitly belong to JsonConfigWriterService
3. Consistency: Follows the same pattern as other refactored methods
4. Maintainability: Easier to understand class interface and responsibilities

Testing Notes

• All functionality preserved - no behavioral changes
• Functions maintain exact same signatures (except for class scope)
• Call sites updated to use this-> pointer
• Namespace changed from json_config_writer to impl to match class namespace

This is part of a broader effort to convert all free functions in json_config_writer_*.cpp files to class methods.
