    • set: function

      • set(value: T): void

        Sets a value

        Parameters

        • value: T

          Value to write

        Returns void

    • onDiff: function

      • onDiff(changes: (changes: PathDataChange<any>[]) => void): () => void

        Notifies of which field(s) were changed. If you just care about the whole, changed data use the value event.

        Use the returned function to unsubscribe.

        Parameters

        • changes: (changes: PathDataChange<any>[]) => void

        Returns () => void

    • onField: function

      • onField(
            fieldName: string,
            handler: (result: ObjectFieldHandler) => void,
        ): () => void

        Notifies when the value of fieldName is changed.

        Use the returned function to unsubscribe.

        Parameters

        • fieldName: string
        • handler: (result: ObjectFieldHandler) => void

        Returns () => void

    • update: function

      • update(changedPart: RecursivePartial<V>): T

        Updates the reactive with some partial key-value pairs. Keys omitted are left the same as the current value.

        Parameters

        • changedPart: RecursivePartial<V>

        Returns T

        Returns new value

    • updateField: function

      • updateField(field: string, value: any): void

        Updates a particular field by its path

        Parameters

        • field: string
        • value: any

        Returns void

    • last: function

      • last(): T

        Returns T

• options: Partial<ElementsOptions>
