Class OperationsGrpc.OperationsFutureStub

  • Enclosing class:
    OperationsGrpc
    public static final class OperationsGrpc.OperationsFutureStub
extends io.grpc.stub.AbstractFutureStub<OperationsGrpc.OperationsFutureStub>
     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.

    • Method Detail

      • listOperations

        public com.google.common.util.concurrent.ListenableFuture<ListOperationsResponse> listOperations​(ListOperationsRequest request)
         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.

      • getOperation

        public com.google.common.util.concurrent.ListenableFuture<Operation> getOperation​(GetOperationRequest request)
         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.

      • deleteOperation

        public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> deleteOperation​(DeleteOperationRequest request)
         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`.

      • cancelOperation

        public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> cancelOperation​(CancelOperationRequest request)
         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`.

      • waitOperation

        public com.google.common.util.concurrent.ListenableFuture<Operation> waitOperation​(WaitOperationRequest request)
         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.
