    Interface LDEmitter

    Implementation Note: There should not be any default listeners for change events in a client implementation. Default listeners mean a client cannot determine when there are actual application developer provided listeners. If we require default listeners, then we should add a system to allow listeners which have counts independent of the primary listener counts.

    interface LDEmitter {
        emit(name: LDEmitterEventName, ...detail: any[]): void;
        eventNames(): string[];
        listenerCount(name: LDEmitterEventName): number;
        off(name: LDEmitterEventName, listener?: (...args: any[]) => void): void;
        on(name: LDEmitterEventName, listener: (...args: any[]) => void): void;
    }
    Index
    emit eventNames listenerCount off on
