Class GcpCallInvokerPool (4.4.0) 

public sealed class GcpCallInvokerPool

A pool of GCP call invokers for the same service, but with potentially different endpoints and/or channel options. Each endpoint/options pair has a single GcpCallInvoker. All call invokers created by this pool use default application credentials. This class is thread-safe.

Constructors

GcpCallInvokerPool(ServiceMetadata)

public GcpCallInvokerPool(ServiceMetadata serviceMetadata)

Creates a call invoker pool which will use the given service metadata to determine scopes and self-signed JWT support.

Parameter
Name Description
serviceMetadata ServiceMetadata

The metadata for the service that this pool will be used with. Must not be null.

Methods

GetCallInvoker(string, GrpcChannelOptions, ApiConfig, GrpcAdapter)

public GcpCallInvoker GetCallInvoker(string endpoint, GrpcChannelOptions options, ApiConfig apiConfig, GrpcAdapter adapter)

Returns a call invoker from this pool, creating a new one if there is no call invoker already associated with endpoint and options.

Parameters
Name Description
endpoint string

The endpoint to connect to. Must not be null.
options GrpcChannelOptions

The options to use for each channel created by the call invoker. May be null.
apiConfig ApiConfig

The API configuration used to determine channel keys. Must not be null.
adapter GrpcAdapter

The gRPC adapter to use to create call invokers. Must not be null.
Returns
Type Description
GcpCallInvoker

A call invoker for the specified endpoint.

GetCallInvokerAsync(string, GrpcChannelOptions, ApiConfig, GrpcAdapter)

public Task<GcpCallInvoker> GetCallInvokerAsync(string endpoint, GrpcChannelOptions options, ApiConfig apiConfig, GrpcAdapter adapter)

Asynchronously returns a call invoker from this pool, creating a new one if there is no call invoker already associated with endpoint and options.

Parameters
Name Description
endpoint string

The endpoint to connect to. Must not be null.
options GrpcChannelOptions

The options to use for each channel created by the call invoker. May be null.
apiConfig ApiConfig

The API configuration used to determine channel keys. Must not be null.
adapter GrpcAdapter

The gRPC adapter to use to create call invokers. Must not be null.
Returns
Type Description
TaskGcpCallInvoker

A task representing the asynchronous operation. The value of the completed task will be a call invoker for the specified endpoint.

ShutdownChannelsAsync()

public Task ShutdownChannelsAsync()

Shuts down all the open channels of all currently-allocated call invokers asynchronously. This does not prevent the call invoker pool from being used later on, but the currently-allocated call invokers will not be reused.

Returns
Type Description
Task

A task which will complete when all the (current) channels have been shut down.
