StateAdapter

Main state adapter that manages both backtest and live state storage.

Features:

• Subscribes to signal lifecycle events (cancelled/closed) to dispose stale instances
• Routes all operations to StateBacktest or StateLive based on dto.backtest
• Singleshot enable pattern prevents duplicate subscriptions
• Cleanup function for proper unsubscription

Properties

enable

enable: (() => (...args: any[]) => any) & ISingleshotClearable<() => (...args: any[]) => any>
Copy

Enables state storage by subscribing to signal lifecycle events. Clears memoized instances in StateBacktest and StateLive when a signal is cancelled or closed, preventing stale instances from accumulating. Uses singleshot to ensure one-time subscription.

disable

disable: () => void
Copy

Disables state storage by unsubscribing from signal lifecycle events. Safe to call multiple times.

getState

getState: <Value extends object = object>(dto: { signalId: string; bucketName: string; initialValue: object; backtest: boolean; }) => Promise<Value>
Copy

Read the current state value for a signal. Routes to StateBacktest or StateLive based on dto.backtest.

setState

setState: <Value extends object = object>(dispatch: Value | Dispatch<Value>, dto: { signalId: string; bucketName: string; initialValue: object; backtest: boolean; }) => Promise<Value>
Copy

Update the state value for a signal. Routes to StateBacktest or StateLive based on dto.backtest.
