Class: ScopedContainer

Defined in: src/DI/scoped-container.ts:14

Hierarchical DI container that supports parent-chain resolution.

Each component with services: [...] in its

Component

config gets a ScopedContainer. Services not found locally are resolved by walking up the parent chain.

Uses topological sort (Kahn’s algorithm) to bootstrap services in correct dependency order — same algorithm as DIContainer.

Constructors

Constructor

new ScopedContainer(parent?: ScopedContainer): ScopedContainer;

Defined in: src/DI/scoped-container.ts:25

Parameters

Returns

ScopedContainer

Accessors

isReady

Get Signature

get isReady(): boolean;

Defined in: src/DI/scoped-container.ts:202

Check if bootstrap has been called.

Returns

boolean

parent

Get Signature

get parent(): ScopedContainer | undefined;

Defined in: src/DI/scoped-container.ts:209

Get the parent container.

Returns

ScopedContainer | undefined

Methods

bootstrap()

bootstrap(): Promise<void>;

Defined in: src/DI/scoped-container.ts:146

Bootstrap all locally registered services, awaiting async onBootstrap hooks. Use this in the DOM init() path where async is available.

Returns

Promise<void>

bootstrapSync()

bootstrapSync(): void;

Defined in: src/DI/scoped-container.ts:123

Bootstrap all locally registered services in dependency order. Each instance is associated with this container via __container.

Services with async onBootstrap() are launched as fire-and-forget. Use the reactive pattern (@Store with isLoading) to handle async state.

Returns

void

dispose()

dispose(): void;

Defined in: src/DI/scoped-container.ts:224

Dispose all local services and reset container. Calls onDestroy() on services that implement it.

Returns

void

get()

get<T>(ctor: Constructor<T>): T;

Defined in: src/DI/scoped-container.ts:166

Resolve a service by walking up the parent chain. Checks local scope first, then parent, then grandparent, etc.

Type Parameters

Parameters

Returns

T

getAllInstances()

getAllInstances(): any[];

Defined in: src/DI/scoped-container.ts:216

Get all locally instantiated service instances.

Returns

any[]

has()

has(ctor: Constructor): boolean;

Defined in: src/DI/scoped-container.ts:186

Check if a service exists in this scope or any parent scope.

Parameters

Returns

boolean

hasLocal()

hasLocal(ctor: Constructor): boolean;

Defined in: src/DI/scoped-container.ts:195

Check if a service is registered locally (not including parents).

Parameters

Returns

boolean

register()

register(token: Constructor): void;

Defined in: src/DI/scoped-container.ts:32

Register a service constructor in this scope

Parameters

Returns

void

registerDependency()

registerDependency(parent: Constructor, dependency: Constructor): void;

Defined in: src/DI/scoped-container.ts:48

Register a dependency relationship between services in this scope. Only for dependencies that are BOTH registered locally. Cross-scope dependencies are resolved via parent chain at get() time.

Parameters

Returns

void
