+<h3>Method Details</h3>
+<div class="method">
+    <code class="details" id="cancel">cancel(name, body=None, x__xgafv=None)</code>
+  <pre>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 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 value with a google.rpc.Status.code of 1,
+corresponding to `Code.CANCELLED`.
+
+Args:
+  name: string, The name of the operation resource to be cancelled. (required)
+  body: object, The request body.
+    The object takes the form of:
+
+{ # The request message for Operations.CancelOperation.
+  }
+
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
+
+Returns:
+  An object of the form:
+
+    { # A generic empty message that you can re-use to avoid defining duplicated
+      # empty messages in your APIs. A typical example is to use it as the request
+      # or the response type of an API method. For instance:
+      #
+      #     service Foo {
+      #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
+      #     }
+      #
+      # The JSON representation for `Empty` is empty JSON object `{}`.
+  }</pre>
+</div>
+
+<div class="method">
+    <code class="details" id="delete">delete(name, x__xgafv=None)</code>
+  <pre>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`.
+
+Args:
+  name: string, The name of the operation resource to be deleted. (required)
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
+
+Returns:
+  An object of the form:
+
+    { # A generic empty message that you can re-use to avoid defining duplicated
+      # empty messages in your APIs. A typical example is to use it as the request
+      # or the response type of an API method. For instance:
+      #
+      #     service Foo {
+      #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);

+  }</pre>
+</div>
+
+<div class="method">
+    <code class="details" id="get">get(name, x__xgafv=None)</code>
+  <pre>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.
+
+Args:
+  name: string, The name of the operation resource. (required)
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format

+</div>
+
+<div class="method">
+    <code class="details" id="list">list(name, pageToken=None, x__xgafv=None, pageSize=None, filter=None)</code>
+  <pre>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.
+
+Args:
+  name: string, The name of the operation's parent resource. (required)
+  pageToken: string, The standard list page token.
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
+  pageSize: integer, The standard list page size.
+  filter: string, The standard list filter.
+
+Returns:
+  An object of the form:
+
+    { # The response message for Operations.ListOperations.
+    "nextPageToken": "A String", # The standard List next-page token.
+    "operations": [ # A list of operations that matches the specified filter in the request.
