Summary

This PR represents the final enhancement to the wrapper class detection system with significantly improved validation logic. The changes introduce a more robust and accurate wrapper class identification system with comprehensive validation criteria.

Major Enhancements

  • Method Refactoring: Renamed and improved core detection methods for clarity
  • Enhanced Validation Logic: More comprehensive checks for wrapper class identification
  • Better Type Checking: Improved collection type detection and JAXBElement exclusion
  • Comprehensive Field Analysis: Better validation of class structure and properties

Technical Improvements

  • Refactored Detection: Renamed checkClassStructure to isWrapperClass with improved logic
  • Static Field Detection: Added checks for static fields in wrapper class candidates
  • Collection Type Validation: Enhanced collection type checking with runtime class validation
  • JAXB Element Exclusion: Explicit exclusion of JAXBElement types from wrapper consideration
  • Comprehensive Annotation Checks: Better validation of conflicting JAXB annotations

Validation Criteria Enhanced

  • Class Structure: Better validation of abstract classes, interfaces, and inheritance
  • Field Analysis: Comprehensive analysis of class fields and their properties
  • Type Safety: Improved type checking with runtime validation
  • Annotation Conflicts: Enhanced detection of conflicting JAXB annotations

Impact

  • Higher Accuracy: More precise identification of wrapper classes
  • Reduced False Positives: Better filtering prevents incorrect class identification
  • Improved Robustness: Enhanced error handling and edge case coverage
  • Better Performance: Optimized detection logic with early termination

Files Changed

  • plugins/src/main/java/io/github/rawvoid/jaxb/plugin/ElementWrapperPlugin.java (98 lines changed)

Improved detection of wrapper classes and added safeguards to prevent removal of classes with active references or nested classes.
…ped classes

Integrated SLF4J logging to record removed and skipped wrapper classes in `ElementWrapperPlugin`. Updated dependencies to include SLF4J.
…g methods

Enhanced `ElementWrapperPlugin` with extensive Javadoc comments, improving clarity for annotation migration, wrapper detection, and field handling logic.
- Fix incomplete removal of wrapper classes in ElementWrapperPlugin
- Improve reference checking logic in removeWrapperClass method to identify all usages
- Enhance debug output formatting for better readability
