Reflection System Overview

Project Summary

The reflection system implements the Dart mirrors API in a cross-platform compatible way. By following the established mirrors API design, we ensure our system provides familiar, comprehensive reflection capabilities while working across all Dart platforms. The implementation follows AI-CDS methodology to ensure high quality, maintainable, and efficient code.

Core Architecture

1. Mirror System

The central entry point following Dart's MirrorSystem design:

abstract class MirrorSystem {
  Map<Uri, LibraryMirror> get libraries;
  LibraryMirror findLibrary(Symbol libraryName);
  IsolateMirror get isolate;
  TypeMirror get dynamicType;
  TypeMirror get voidType;
  TypeMirror get neverType;
}

2. Core Mirrors

The fundamental reflection capabilities:

abstract class Mirror {}

abstract class DeclarationMirror implements Mirror {
  Symbol get simpleName;
  Symbol get qualifiedName;
  DeclarationMirror? get owner;
  bool get isPrivate;
  bool get isTopLevel;
  List<InstanceMirror> get metadata;
}

abstract class ObjectMirror implements Mirror {
  InstanceMirror invoke(Symbol memberName, List positionalArgs, [Map<Symbol, dynamic> namedArgs]);
  InstanceMirror getField(Symbol fieldName);
  InstanceMirror setField(Symbol fieldName, Object? value);
}

3. Type System

Complete type reflection support:

abstract class TypeMirror implements DeclarationMirror {
  bool get hasReflectedType;
  Type get reflectedType;
  List<TypeVariableMirror> get typeVariables;
  List<TypeMirror> get typeArguments;
  bool get isOriginalDeclaration;
  TypeMirror get originalDeclaration;
  bool isSubtypeOf(TypeMirror other);
  bool isAssignableTo(TypeMirror other);
}
