接触数コード解析

「陽性者との接触を確認する」をクリックした時

ホーム画面から「陽性者との接触を確認する」をクリックしたときは、

1. UserDataModel::ExposureInformation コレクションの数を調べる

PlatformScheduleFetch ->> ExposureNotification(share): UpdateKeysFromServer
ExposureNotification(share) ->> ExposureNotificationHandler: FetchExposureKeyBatchFilesFromServerAsync(submitBatches)
ExposureNotificationHandler ->> ExposureNotificationHandler: DownloadBatchAsync
ExposureNotificationHandler -->> ExposureNotificationHandler: downloadedFiles
ExposureNotificationHandler ->> ExposureNotificationHandler: downloadedFiles.Count > 0

ExposureNotificationHandler ->> ExposureNotification(share): submitBatches: callback

```mermaid
sequenceDiagram
HomePageView ->> HomePageViewModel: OnClickExposures
HomePageViewModel ->> ExposureNotificationService: GetExposureCount()
ExposureNotificationService ->> UserDataModel: ExposureInformation.Count()

Note right of UserDataModel: UserDataModel::ExposureInformationに保持される 

UserDataModel -->> ExposureNotificationService: count
ExposureNotificationService -->> HomePageViewModel: count
