Methods

`Protected` `Abstract`_createEventEmitter

_createEventEmitter(): GenericEventEmitter<AnyProviderEvent, Record<string, unknown>>
Returns GenericEventEmitter<AnyProviderEvent, Record<string, unknown>>
- Defined in packages/shared/src/open-feature.ts:96

addHandler

addHandler<T>(eventType, handler): void
Adds a handler for the given provider event type. The handlers are called in the order they have been added. API (global) events run for all providers.
Type Parameters
- T extends AnyProviderEvent
Parameters
- eventType: T
  The provider event type to listen to
- handler: EventHandler<ServerProviderEvents | ClientProviderEvents>
  The handler to run on occurrence of the event type
Returns void
Implementation of Eventing.addHandler
- Defined in packages/shared/src/open-feature.ts:158

addHooks

addHooks(...hooks): this
Adds hooks that will run during flag evaluations on this receiver. Hooks are executed in the order they were registered. Adding additional hooks will not remove existing hooks. Hooks registered on the global API object run with all evaluations. Hooks registered on the client run with all evaluations on that client.
Parameters
- Rest...hooks: H[]
  A list of hooks that should always run
Returns this
The receiver (this object)
Implementation of EvaluationLifeCycle.addHooks
- Defined in packages/shared/src/open-feature.ts:114

Parameters
- Optionaldomain: string
Returns GenericEventEmitter<AnyProviderEvent, Record<string, unknown>>
- Defined in packages/shared/src/open-feature.ts:318

clearHandlers

clearHandlers(): void
Removes all event handlers.

Returns void
- Defined in packages/shared/src/open-feature.ts:190

clearHooks

clearHooks(): this
Clears all the hooks that are registered on this receiver.

Returns this
The receiver (this object)

Gets the current handlers for the given provider event type.
Type Parameters
- T extends AnyProviderEvent
Parameters
- eventType: T
  The provider event type to get the current handlers for
Returns EventHandler<ServerProviderEvents | ClientProviderEvents>[]
The handlers currently attached to the given provider event type
Implementation of Eventing.getHandlers

setLogger

setLogger(logger): this
Sets a logger on this receiver. This logger supersedes to the global logger and is passed to various components in the SDK. The logger configured on the global API object will be used for all evaluations, unless overridden in a particular client.
Parameters
