public abstract class TetherClient
Tether client wrapper, for convenient use.
Derived Types
Namespace
Google.Cloud.ApigeeConnect.V1Assembly

Remarks
Tether provides a way for the control plane to send HTTP API requests to services in data planes that runs in a remote datacenter without requiring customers to open firewalls on their runtime plane.
Properties
DefaultEndpoint
public static string DefaultEndpoint { get; }
The default endpoint for the Tether service, which is a host of "apigeeconnect.googleapis.com" and a port of 443.

Methods
Create()
public static TetherClient Create()
Synchronously creates a TetherClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use TetherClientBuilder.
Returns | |
---|---|
Type | Description |
TetherClient | The created TetherClient. |
CreateAsync(CancellationToken)
public static Task<TetherClient> CreateAsync(CancellationToken cancellationToken = default(CancellationToken))
Asynchronously creates a TetherClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use TetherClientBuilder.
Parameter | |
---|---|
Name | Description |
cancellationToken | CancellationToken The CancellationToken to use while creating the client. |
Returns | |
---|---|
Type | Description |
Task<TetherClient> | The task representing the created TetherClient. |
Egress(CallSettings, BidirectionalStreamingSettings)
public virtual TetherClient.EgressStream Egress(CallSettings callSettings = null, BidirectionalStreamingSettings streamingSettings = null)
Egress streams egress requests and responses. Logically, this is not actually a streaming request, but uses streaming as a mechanism to flip the client-server relationship of gRPC so that the server can act as a client. The listener, the RPC server, accepts connections from the dialer, the RPC client. The listener streams http requests and the dialer streams http responses.
Parameters | |
---|---|
Name | Description |
callSettings | CallSettings If not null, applies overrides to this RPC call. |
streamingSettings | BidirectionalStreamingSettings If not null, applies streaming overrides to this RPC call. |
Returns | |
---|---|
Type | Description |
TetherClient.EgressStream | The client-server stream. |
// Create client
TetherClient tetherClient = TetherClient.Create();
// Initialize streaming call, retrieving the stream object
TetherClient.EgressStream response = tetherClient.Egress();
// Sending requests and retrieving responses can be arbitrarily interleaved
// Exact sequence will depend on client/server behavior
// Create task to do something with responses from server
Task responseHandlerTask = Task.Run(async () =>
{
// Note that C# 8 code can use await foreach
AsyncResponseStream<EgressRequest> responseStream = response.GetResponseStream();
while (await responseStream.MoveNextAsync())
{
EgressRequest responseItem = responseStream.Current;
// Do something with streamed response
}
// The response stream has completed
});
// Send requests to the server
bool done = false;
while (!done)
{
// Initialize a request
EgressResponse request = new EgressResponse
{
Id = "",
HttpResponse = new HttpResponse(),
Status = new Status(),
Project = "",
TraceId = "",
Endpoint = TetherEndpoint.Unspecified,
Name = "",
};
// Stream a request to the server
await response.WriteAsync(request);
// Set "done" to true when sending requests is complete
}
// Complete writing requests to the stream
await response.WriteCompleteAsync();
// Await the response handler
// This will complete once all server responses have been processed
await responseHandlerTask;
ShutdownDefaultChannelsAsync()
public static Task ShutdownDefaultChannelsAsync()
Shuts down any channels automatically created by Create() and CreateAsync(CancellationToken). Channels which weren't automatically created are not affected.
Returns | |
---|---|
Type | Description |
Task | A task representing the asynchronous shutdown operation. |
After calling this method, further calls to Create() and CreateAsync(CancellationToken) will create new channels, which could in turn be shut down by another call to this method.
