type

type: ProviderType | TokenProvider;

Token group provider to retrieve all provider from the same type

deps

deps: TokenProvider[];

imports:

get useClass

get useClass(): Type<T>;

set useClass

set useClass(value: Type<T> | AbstractType<T>);

Create a new store if the given value is a class. Otherwise, the value is ignored.

• key (string): The key to look up

Retrieves a value from the provider's store.

get

get<Type = unknown>(key: string, defaultValue: Type): Type;

• key (string): The key to look up

• defaultValue (Type): The value to return if key is not found

Retrieves a value from the provider's store with a default fallback.

isAsync

isAsync(): boolean;

clone
