# 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:
|
||
|
|
```dart
|
||
|
|
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:
|
||
|
|
```dart
|
||
|
|
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:
|
||
|
|
```dart
|
||
|
|
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);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
