How to use the @here/harp-mapview.TileLoaderState.Canceled function in @here/harp-mapview

protected onError(error: Error) {
        if (this.state === TileLoaderState.Canceled) {
            // If we're canceled, we should simply ignore any state transitions and errors from
            // underlying load/decode ops.
            return;
        }
        const dataSource = this.dataSource;

            `[${dataSource.name}]: failed to load tile ${this.tileKey.mortonCode()}`,
            error
        );

        this.error = error;

        this.onDone(TileLoaderState.Failed);
    }
}
