Simple Class Reflection + +```dart +import 'package:platform_reflection/reflection.dart'; + +// 1.

Property Access + +```dart +// Get property value +final mirror = reflector.reflect(instance); +final name = mirror.getField(const Symbol('name')).reflectee as String; + +// Set property value +mirror.setField(const Symbol('name'), 'Jane'); + +// Check if property exists +final metadata = Reflector.getPropertyMetadata(User); +if (metadata?.containsKey('name') ?? false) { + // Property exists +} +``` + +### 3. Method Invocation + +```dart +// Invoke method without arguments +mirror.invoke(const Symbol('birthday'), []); + +// Invoke method with arguments +final result = mirror.invoke( + const Symbol('greet'), + ['Hello'], +).reflectee as String; + +// Invoke method with named arguments +final result = mirror.invoke( + const Symbol('update'), + [], + {const Symbol('value'): 42}, +).reflectee; +``` + +### 4. Constructor Usage + +```dart +// Default constructor +final instance = reflector.createInstance( + User, + positionalArgs: ['John', 30], +) as User; + +// Named constructor +final instance = reflector.createInstance( + User, + constructorName: 'guest', +) as User; + +// Constructor with named arguments +final instance = reflector.createInstance( + User, + positionalArgs: ['John'], + namedArgs: {const Symbol('age'): 30}, +) as User; +``` + +### 5. Type Information + +```dart +// Get type metadata +final metadata = Reflector.getTypeMetadata(User); + +// Check properties +for (var property in metadata.properties.values) { + print('${property.name}: ${property.type}'); +} + +// Check methods +for (var method in metadata.methods.values) { + print('${method.name}(${method.parameterTypes.join(', ')})'); +} +``` + +### 6. Error Handling + +```dart +try { + // Attempt reflection + final mirror = reflector.reflect(instance); + mirror.invoke(const Symbol('method'), []); +} on NotReflectableException catch (e) { + print('Type not registered: $e'); +} on MemberNotFoundException catch (e) { + print('Member not found: $e'); +} on InvalidArgumentsException catch (e) { + print('Invalid arguments: $e'); +} on ReflectionException catch (e) { + print('Reflection error: $e'); +} +``` + +## Common Patterns + +### 1. Registration Helper + +```dart +void registerType(Type type) { + Reflector.register(type); + + final scanner = Scanner(); + final metadata = scanner.scanType(type); + + // Register properties + for (var property in metadata.properties.values) { + Reflector.registerProperty( + type, + property.name, + property.type, + isWritable: property.isWritable, + ); + } + + // Register methods + for (var method in metadata.methods.values) { + Reflector.registerMethod( + type, + method.name, + method.parameterTypes, + method.returnsVoid, + parameterNames: method.parameters.map((p) => p.name).toList(), + isRequired: method.parameters.map((p) => p.isRequired).toList(), + ); + } +} +``` + +### 2. Property Observer + +```dart +class PropertyObserver { + final InstanceMirror mirror; + final Symbol propertyName; + final void Function(dynamic oldValue, dynamic newValue) onChange; + + PropertyObserver(this.mirror, this.propertyName, this.onChange); + + void observe() { + var lastValue = mirror.getField(propertyName).reflectee; + + Timer.periodic(Duration(milliseconds: 100), (_) { + final currentValue = mirror.getField(propertyName).reflectee; + if (currentValue != lastValue) { + onChange(lastValue, currentValue); + lastValue = currentValue; + } + }); + } +} +``` + +### 3. Method Interceptor + +```dart +class MethodInterceptor { + final InstanceMirror mirror; + final Symbol methodName; + final void Function(List args, Map named) beforeInvoke; + final void Function(dynamic result) afterInvoke; + + MethodInterceptor( + this.mirror, + this.methodName, + {this.beforeInvoke = _noOp, + this.afterInvoke = _noOp}); + + static void _noOp([dynamic _]) {} + + dynamic invoke(List args, [Map? named]) { + beforeInvoke(args, named ?? {}); + final result = mirror.invoke(methodName, args, named).reflectee; + afterInvoke(result); + return result; + } +} +``` + +## Best Practices + +1. **Register Early** + ```dart + void main() { + // Register all types at startup + registerType(); + registerType(); + registerType(); + + // Start application + runApp(); + } + ``` + +2. **Cache Mirrors** + ```dart + class UserService { + final Map _mirrors = {}; + + InstanceMirror getMirror(User user) { + return _mirrors.putIfAbsent( + user, + () => reflector.reflect(user), + ); + } + } + ``` + +3. **Handle Errors** + ```dart + T reflectSafely(Function() operation, T defaultValue) { + try { + return operation() as T; + } on ReflectionException catch (e) { + print('Reflection failed: $e'); + return defaultValue; + } + } + ``` + +4. **Validate Registration** + ```dart + bool isFullyRegistered(Type type) { + final metadata = Reflector.getTypeMetadata(type); + if (metadata == null) return false; + + // Check properties + if (metadata.properties.isEmpty) return false; + + // Check methods + if (metadata.methods.isEmpty) return false; + + // Check constructors + if (metadata.constructors.isEmpty) return false; + + return true; + } + ``` + +## Common Issues + +1. **Type Not Registered** + ```dart + // Wrong + reflector.reflect(unregisteredInstance); + + // Right + Reflector.register(UnregisteredType); + reflector.reflect(instance); + ``` + +2. **Missing Property/Method Registration** + ```dart + // Wrong + Reflector.register(User); + + // Right + Reflector.register(User); + Reflector.registerProperty(User, 'name', String); + Reflector.registerMethod(User, 'greet', [String]); + ``` + +3. **Wrong Argument Types** + ```dart + // Wrong + mirror.invoke(const Symbol('greet'), [42]); + + // Right + mirror.invoke(const Symbol('greet'), ['Hello']); + ``` + +## Performance Tips + +1. **Cache Metadata** + ```dart + final metadata = Reflector.getTypeMetadata(User); + final properties = metadata.properties; + final methods = metadata.methods; + ``` + +2. **Reuse Mirrors** + ```dart + final mirror = reflector.reflect(instance); + // Reuse mirror for multiple operations + ``` + +3. **Batch Registration** + ```dart + void registerAll() { + for (var type in types) { + registerType(type); + } + } + ``` + +## Next Steps + +- Read the [Technical Specification](technical_specification.md) for detailed implementation information +- Check the [API Reference](../README.md#api-reference) for complete API documentation +- See the [Mirrors Comparison](mirrors_comparison.md) for differences from dart:mirrors diff --git a/incubation/reflection/doc/roadmap.md b/incubation/reflection/doc/roadmap.md new file mode 100644 index 0000000..8f012c8 --- /dev/null +++ b/incubation/reflection/doc/roadmap.md @@ -0,0 +1,294 @@ +# Platform Reflection Roadmap + +This document outlines the planned improvements and future direction of the Platform Reflection library. + +## Current Status (v0.1.0) + +### Implemented Features +✅ Basic reflection system +✅ Property access/mutation +✅ Method invocation +✅ Constructor handling +✅ Type introspection +✅ Basic metadata support +✅ Error handling +✅ Cross-platform support + +### Known Limitations +❌ No cross-isolate reflection +❌ Limited generic support +❌ No source location tracking +❌ No extension method support +❌ No mixin composition +❌ Limited metadata capabilities +❌ No dynamic proxy generation +❌ No attribute-based reflection + +## Short-term Goals (v0.2.0) + +### 1.

// First user's name +dataGet(data, 'users.{last}.name'); // Last user's name + +// Wildcard operations +dataGet(data, 'users.*.profile.age'); // All users' ages +dataSet(data, 'users.*.active', true); // Set all users active +``` + +### Helper Functions + +```dart +// Get first/last elements +head([1, 2, 3]); // 1 +last([1, 2, 3]); // 3 + +// Create collection from iterable +final collection = collect([1, 2, 3]); + +// Get value from factory +final value = value(() => computeValue()); +``` + +### List Operations + +The Collection class implements Dart's `ListMixin`, providing all standard list operations: + +```dart +final list = Collection(['a', 'b', 'c']); + +// Add/remove items +list.add('d'); +list.remove('b'); + +// Access by index +list[0] = 'A'; +final first = list[0]; + +// Standard list methods +list.length; +list.isEmpty; +list.reversed; +``` + +### Helper Methods + +```dart +// Get random items +collection.random(); // Single random item +collection.random(3); // Multiple random items + +// Join items +collection.joinWith(', '); // Custom join with separator + +// Cross join collections +final colors = Collection(['red', 'blue']); +final sizes = Collection(['S', 'M']); +colors.crossJoin([sizes]); // All combinations +``` + +## Important Notes + +1. The Collection class is generic and maintains type safety: + ```dart + final numbers = Collection([1, 2, 3]); + final strings = Collection(['a', 'b', 'c']); + ``` + +2. Most methods return a new Collection instance, keeping the original unchanged: + ```dart + final original = Collection([1, 2, 3]); + final doubled = original.mapItems((n) => n * 2); // Original unchanged + ``` + +3. The class implements `ListMixin`, so it can be used anywhere a List is expected: + ```dart + void processList(List list) { + // Works with Collection + } + ``` + +4.
