Firestore v1 API - Class FirestoreClientImpl (3.8.0) 

public sealed class FirestoreClientImpl : FirestoreClient

Reference documentation and code samples for the Firestore v1 API class FirestoreClientImpl.

Firestore client wrapper implementation, for convenient use.

Inheritance

object > FirestoreClient > FirestoreClientImpl

Namespace

Google.Cloud.Firestore.V1

Assembly

Google.Cloud.Firestore.V1.dll

Remarks

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.

Constructors

FirestoreClientImpl(FirestoreClient, FirestoreSettings, ILogger)

public FirestoreClientImpl(Firestore.FirestoreClient grpcClient, FirestoreSettings settings, ILogger logger)

Constructs a client wrapper for the Firestore service, with the specified gRPC client and settings.

Parameters
Name Description
grpcClient FirestoreFirestoreClient

The underlying gRPC client.
settings FirestoreSettings

The base FirestoreSettings used within this client.
logger ILogger

Optional ILogger to use within this client.

Fields

ResourcePrefixHeader

[Obsolete("This header is obsolete; x-goog-request-params should now be used instead. This constant will be removed in a future version")]
public const string ResourcePrefixHeader = "google-cloud-resource-prefix"

The name of the header used for efficiently routing requests.

Field Value
Type Description
string
Remarks

This should be set to the database resource name ("projects/{projectId}/databases/{databaseId}") for any RPC. For non-streaming calls, FirestoreClientImpl performs this automatically. This cannot be performed automatically for streaming calls due to the separation between initializing the stream and sending requests, so client code should set the value in a CallSettings. Typically this is performed with either the FromHeader(string, string) factory method or the WithHeader(CallSettings, string, string) extension method.

Properties

GrpcClient

public override Firestore.FirestoreClient GrpcClient { get; }

Methods

BatchGetDocuments(BatchGetDocumentsRequest, CallSettings)

public override FirestoreClient.BatchGetDocumentsStream BatchGetDocuments(BatchGetDocumentsRequest request, CallSettings callSettings = null)

Gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

Parameters
Name Description
request BatchGetDocumentsRequest

The request object containing all of the parameters for the API call.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
FirestoreClientBatchGetDocumentsStream

Overrides

BatchWrite(BatchWriteRequest, CallSettings)

public override BatchWriteResponse BatchWrite(BatchWriteRequest request, CallSettings callSettings = null)

Applies a batch of write operations.

The BatchWrite method does not apply the write operations atomically and can apply them out of order. Method does not allow more than one write per document. Each write succeeds or fails independently. See the [BatchWriteResponse][google.firestore.v1.BatchWriteResponse] for the success status of each write.

If you require an atomically applied set of writes, use [Commit][google.firestore.v1.Firestore.Commit] instead.

request BatchWriteRequest

The request object containing all of the parameters for the API call.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
BatchWriteResponse

The RPC response.
