public sealed class PredictionServiceClientImpl : PredictionServiceClient

Reference documentation and code samples for the Google AutoML v1 API class PredictionServiceClientImpl.

PredictionService client wrapper implementation, for convenient use.

Inheritance

object > PredictionServiceClient > PredictionServiceClientImpl

Namespace

Google.Cloud.AutoML.V1

Assembly

Remarks

AutoML Prediction API.

On any input that is documented to expect a string parameter in snake_case or dash-case, either of those cases is accepted.

Constructors

PredictionServiceClientImpl(PredictionServiceClient, PredictionServiceSettings, ILogger)

public PredictionServiceClientImpl(PredictionService.PredictionServiceClient grpcClient, PredictionServiceSettings settings, ILogger logger)

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

Parameters
Name Description
grpcClient PredictionServicePredictionServiceClient

The underlying gRPC client.
settings PredictionServiceSettings

The base PredictionServiceSettings used within this client.
logger ILogger

Optional ILogger to use within this client.

Methods

BatchPredict(BatchPredictRequest, CallSettings)

public override Operation<BatchPredictResult, OperationMetadata> BatchPredict(BatchPredictRequest request, CallSettings callSettings = null)

Perform a batch prediction. Unlike the online [Predict][google.cloud.automl.v1.PredictionService.Predict], batch prediction result won't be immediately available in the response. Instead, a long running operation object is returned. User can poll the operation result via [GetOperation][google.longrunning.Operations.GetOperation] method. Once the operation is done, [BatchPredictResult][google.cloud.automl.v1.BatchPredictResult] is returned in the [response][google.longrunning.Operation.response] field. Available for following ML scenarios:

  • AutoML Vision Classification
  • AutoML Vision Object Detection
  • AutoML Video Intelligence Classification
  • AutoML Video Intelligence Object Tracking * AutoML Natural Language Classification
  • AutoML Natural Language Entity Extraction
  • AutoML Natural Language Sentiment Analysis
  • AutoML Tables
Parameters
Name Description
request BatchPredictRequest

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
OperationBatchPredictResultOperationMetadata

The RPC response.
Overrides

BatchPredictAsync(BatchPredictRequest, CallSettings)

public override Task<Operation<BatchPredictResult, OperationMetadata>> BatchPredictAsync(BatchPredictRequest request, CallSettings callSettings = null)
