Reference documentation and code samples for the Firestore v1 API class Firestore.
The Cloud Firestore service.
Cloud Firestore is a fast, fully managed, serverless, cloud-native NoSQL
document database that simplifies storing, syncing, and querying data for
your mobile, web, and IoT apps at global scale. Its client libraries provide
live synchronization and offline support, while its security features and
integrations with Firebase and Google Cloud Platform accelerate building
truly serverless apps.
public static void BindService(ServiceBinderBase serviceBinder, Firestore.FirestoreBase serviceImpl)
Register service method with a service binder with or without implementation. Useful when customizing the service binding logic.
Note: this method is part of an experimental API that can change or be removed without any prior notice.
