ClassType<T> class

The ClassType class in Jetleaf represents a reference to a Dart class, optionally including metadata such as package, protection domain, or type declaration.

It provides a convenient way to convert a class reference into a Class instance used by the Jetleaf framework for reflection, conditional processing, or pod registration. ClassType serves as a bridge between compile-time type information and runtime class metadata in JetLeaf's type system infrastructure.

Key Features:

  • Supports optional class name, package, ProtectionDomain, and ClassDeclaration.
  • Can convert itself into a Class instance using toClass.
  • Integrates with Jetleaf's type system for dynamic class handling.
  • Provides multiple factory constructors for flexible class reference creation.
  • Supports equality and hash code operations for use in collections.

Usage Example:

import 'package:jetleaf/jetleaf.dart';

// Create a ClassType by name
final simpleClass = ClassType(name: 'UserService');

// Convert to a Jetleaf Class instance
final userClass = simpleClass.toClass();

// Create a ClassType with a ClassDeclaration
final declaredClass = ClassType(declaration: someTypeDeclaration);
final declaredClassInstance = declaredClass.toClass();

// Use in pod registration
@Pod
class ServiceConfiguration {
  @Provide
  UserService userService() => UserService();

  @Provide
  ClassType<UserService> userServiceType() => ClassType<UserService>();
}

Constructors

ClassType([String? package, String? name, ProtectionDomain? pd, ClassDeclaration? declaration, String? qualifiedName])
The ClassType class in Jetleaf represents a reference to a Dart class, optionally including metadata such as package, protection domain, or type declaration.
const
ClassType.declared(ClassDeclaration? declaration, [String? qualifiedName, String? name, ProtectionDomain? pd, String? package])
Creates a ClassType from a ClassDeclaration.
const
ClassType.named(String? name, String? package, [String? qualifiedName, ProtectionDomain? pd, ClassDeclaration? declaration])
Creates a ClassType from a class name and package.
const
ClassType.qualified(String? qualifiedName, [String? name, ProtectionDomain? pd, ClassDeclaration? declaration, String? package])
Creates a ClassType from a fully qualified class name.
