Reflection

Overview

Reflection helpers with cached metadata and property accessors.

Architecture

  • ClassInfo caches fields and methods for faster reflection.
  • PropertyAccessor resolves getters/setters via conventions or annotations.
  • ReflectionUtils offers convenient get/set operations and method lookups.

How to use
