🔍 问题说明

Poorly documented large function

This rule finds large functions that have too few comment lines. Documentation becomes more important as a function becomes more complex, and a lack of documentation makes it harder to maintain.

Recommendation

Add comments to document the purpose of the function. Large, complex functions in particular require detailed documentation, not only because they are harder to understand, but the process of documentation may reveal that the function could be split into smaller, more cohesive functions.

🤖 AI 修复思路

To fix this without changing behavior, add meaningful inline documentation inside ModuleConfigure_Json_File that explains each major processing phase and key assumptions, rather than changing logic. Keep the existing function and code paths intact; just improve maintainability by documenting: parameter validation and error contract, file I/O limits (fixed buffer read), JSON parse stage, and configuration field extraction.

Best concrete fix in XEngine_Source/XEngine_ModuleConfigure/ModuleConfigure_Json/ModuleConfigure_Json.cpp:

• Update comments around ModuleConfigure_Json_File (line 43 onward).
• Add a short function-level note before the body describing workflow and error signaling (Config_IsErrorOccur / Config_dwErrorCode).
• Add block/line comments before each major section:
  1. input validation,
  2. JSON parser setup,
  3. file open/read/close behavior,
  4. parsing and parse-failure behavior,
  5. config field mapping and return behavior.
• Do not alter any variable names, control flow, or assignments.

No new imports, methods, or dependencies are needed.
