AssetLoaderRegistry

AssetLoaderRegistry maps each persistent kind to one loader and one shared AssetType token.

API

class AssetLoaderRegistry {
  readonly size: number;

  register<TValue>(
    type: AssetType<TValue>,
    loader: AssetLoader<TValue>
  ): this;

  has(type: AssetType<unknown>): boolean;
  get<TValue>(type: AssetType<TValue>): AssetLoader<TValue>;
}

register() returns the registry for chaining. Registering any second loader for the same kind throws AssetLoaderAlreadyExistsError.

has() returns true only when the kind and token object both match.

get() preserves the value type carried by the token. It throws AssetLoaderNotFoundError when the kind is absent and AssetTypeMismatchError when the kind was registered with another token object.

const loaders = new AssetLoaderRegistry()
  .register(MODEL_ASSET, modelLoader)
  .register(AUDIO_ASSET, audioLoader);
