Class DynMapReducerDerived<K, T>

    Provides the base implementation derived reducer for Maps / DynMapReducer.

    Note: That you should never directly create an instance of a derived reducer, but instead use the DynMapReducerDerived.initialize function to set up any initial state in a custom derived reducer.

    Type Parameters

    • K = unknown

      unknown - Key type. Defaults to unknown to enforce type safety when no type is specified.

    • T = unknown

      unknown - Type of data. Defaults to unknown to enforce type safety when no type is specified.

    reversed

    • get reversed(): boolean

    • Returns boolean

      Returns current reversed state.

    • set reversed(reversed: boolean): void

    • Sets reversed state and notifies subscribers.

      Parameters

      • reversed: boolean

        New reversed state.

      Returns void

    Protectedinitialize

    • initialize(optionsRest?: { [key: string]: any }): void
    • Protected

      Provides a callback for custom derived reducers to initialize any data / custom configuration. This allows child classes to avoid implementing the constructor.

      Parameters

      • OptionaloptionsRest: { [key: string]: any }

        Any additional custom options passed beyond DynDataOptions.

      Returns void

    subscribe

    • subscribe(handler: (value: this) => void): () => void

    • Subscribe to this DerivedMapReducer.

      Parameters

      • handler: (value: this) => void

        Callback function that is invoked on update / changes. Receives this reference.

      Returns () => void

      Unsubscribe function.
