Assembly

Google.LongRunning.dll

Remarks

Manages long-running operations with an API service.

When an API method normally takes long time to complete, it can be designed to return [Operation][google.longrunning.Operation] to the client, and the client can use this interface to receive the real response asynchronously by polling the operation resource, or pass the operation resource to another API (such as Google Cloud Pub/Sub API) to receive the response. Any API service that returns long-running operations should implement the Operations interface so developers can have a consistent client experience.

Methods

CancelOperation(CancelOperationRequest, CallSettings)

public override void CancelOperation(CancelOperationRequest request, CallSettings callSettings = null)

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use [Operations.GetOperation][google.longrunning.Operations.GetOperation] or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an [Operation.error][google.longrunning.Operation.error] value with a [google.rpc.Status.code][google.rpc.Status.code] of 1, corresponding to Code.CANCELLED.

Parameters
Name	Description
request	CancelOperationRequest The request object containing all of the parameters for the API call.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Overrides

OperationsClient.CancelOperation(CancelOperationRequest, CallSettings)

CancelOperationAsync(CancelOperationRequest, CallSettings)

public override Task CancelOperationAsync(CancelOperationRequest request, CallSettings callSettings = null)

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use [Operations.GetOperation][google.longrunning.Operations.GetOperation] or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an [Operation.error][google.longrunning.Operation.error] value with a [google.rpc.Status.code][google.rpc.Status.code] of 1, corresponding to Code.CANCELLED.

Parameters
Name	Description
request	CancelOperationRequest 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
Task	A Task containing the RPC response.

Overrides

OperationsClient.CancelOperationAsync(CancelOperationRequest, CallSettings)

DeleteOperation(DeleteOperationRequest, CallSettings)

public override void DeleteOperation(DeleteOperationRequest request, CallSettings callSettings = null)

Deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Parameters
Name	Description
request	DeleteOperationRequest The request object containing all of the parameters for the API call.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Overrides

OperationsClient.DeleteOperation(DeleteOperationRequest, CallSettings)

DeleteOperationAsync(DeleteOperationRequest, CallSettings)

public override Task DeleteOperationAsync(DeleteOperationRequest request, CallSettings callSettings = null)

Deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Parameters
Name	Description
request	DeleteOperationRequest 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
Task	A Task containing the RPC response.

Overrides

OperationsClient.DeleteOperationAsync(DeleteOperationRequest, CallSettings)

GetEffectiveCallSettingsForGetOperation(CallSettings)

protected override CallSettings GetEffectiveCallSettingsForGetOperation(CallSettings callSettings)

Return the CallSettings that would be used by a call to GetOperation(GetOperationRequest, CallSettings), using the base settings of this client and the specified per-call overrides.

Parameter
Name	Description
callSettings	CallSettings The per-call override, if any.

Returns
Type	Description
CallSettings	The effective call settings for a GetOperation RPC.

Overrides

OperationsClient.GetEffectiveCallSettingsForGetOperation(CallSettings)

Remarks

This method is used when polling, to determine the appropriate timeout and cancellation token to use for each call.

GetOperation(GetOperationRequest, CallSettings)

public override Operation GetOperation(GetOperationRequest request, CallSettings callSettings = null)

Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.

Parameters
Name	Description
request	GetOperationRequest 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
Operation	The RPC response.

Overrides

GetOperationAsync(GetOperationRequest, CallSettings)

public override Task<Operation> GetOperationAsync(GetOperationRequest request, CallSettings callSettings = null)

Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.

Parameters
Name	Description
request	GetOperationRequest 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
Task<Operation>	A Task containing the RPC response.

Overrides

ListOperations(ListOperationsRequest, CallSettings)

public override PagedEnumerable<ListOperationsResponse, Operation> ListOperations(ListOperationsRequest request, CallSettings callSettings = null)

Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED.

NOTE: the name binding allows API services to override the binding to use different resource name schemes, such as users/*/operations. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

Parameters
Name	Description
request	ListOperationsRequest 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
PagedEnumerable<ListOperationsResponse, Operation>	A pageable sequence of Operation resources.

Overrides

OperationsClient.ListOperations(ListOperationsRequest, CallSettings)

ListOperationsAsync(ListOperationsRequest, CallSettings)

public override PagedAsyncEnumerable<ListOperationsResponse, Operation> ListOperationsAsync(ListOperationsRequest request, CallSettings callSettings = null)

Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED.

NOTE: the name binding allows API services to override the binding to use different resource name schemes, such as users/*/operations. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

Parameters
Name	Description
request	ListOperationsRequest 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
PagedAsyncEnumerable<ListOperationsResponse, Operation>	A pageable asynchronous sequence of Operation resources.

Overrides

OperationsClient.ListOperationsAsync(ListOperationsRequest, CallSettings)

WaitOperation(WaitOperationRequest, CallSettings)

public override Operation WaitOperation(WaitOperationRequest request, CallSettings callSettings = null)

Waits until the specified long-running operation is done or reaches at most a specified timeout, returning the latest state. If the operation is already done, the latest state is immediately returned. If the timeout specified is greater than the default HTTP/RPC timeout, the HTTP/RPC timeout is used. If the server does not support this method, it returns google.rpc.Code.UNIMPLEMENTED. Note that this method is on a best-effort basis. It may return the latest state before the specified timeout (including immediately), meaning even an immediate response is no guarantee that the operation is done.

Parameters
Name	Description
request	WaitOperationRequest 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
Operation	The RPC response.

WaitOperationAsync(WaitOperationRequest, CallSettings)

public override Task<Operation> WaitOperationAsync(WaitOperationRequest request, CallSettings callSettings = null)

Waits until the specified long-running operation is done or reaches at most a specified timeout, returning the latest state. If the operation is already done, the latest state is immediately returned. If the timeout specified is greater than the default HTTP/RPC timeout, the HTTP/RPC timeout is used. If the server does not support this method, it returns google.rpc.Code.UNIMPLEMENTED. Note that this method is on a best-effort basis. It may return the latest state before the specified timeout (including immediately), meaning even an immediate response is no guarantee that the operation is done.
