waitOperation method
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.
Implementation
$grpc.ResponseFuture<$0.Operation> waitOperation(
$0.WaitOperationRequest request, {
$grpc.CallOptions? options,
}) {
return $createUnaryCall(_$waitOperation, request, options: options);
}
