# Genomics API . operations

## Instance Methods

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. Clients may use Operations.GetOperation or Operations.ListOperations to check whether the cancellation succeeded or the operation completed despite cancellation.

Gets the latest state of a long-running operation. Clients can use this

Lists operations that match the specified filter in the request.

Retrieves the next page of results.

### Method Details

`cancel(name, body, x__xgafv=None)`

    Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. Clients may use Operations.GetOperation or Operations.ListOperations to check whether the cancellation succeeded or the operation completed despite cancellation.

    Args:
      name: string, The name of the operation resource to be cancelled. (required)
      body: object, The request body. (required)
        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 `{}`.
      }

`get(name, x__xgafv=None)`

    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

    Returns:
      An object of the form:

        { # This resource represents a long-running operation that is the result of a
          # network API call.
        "metadata": { # An OperationMetadata object. This will always be returned with the Operation.
          "a_key": "", # Properties of the object. Contains field @type with type URL.
        },
        "error": { # The `Status` type defines a logical error model that is suitable for different # The error result of the operation in case of failure or cancellation.
            # programming environments, including REST APIs and RPC APIs. It is used by
            # [gRPC](https://github.com/grpc). The error model is designed to be:
            #
            # - Simple to use and understand for most users
            # - Flexible enough to meet unexpected needs
            #
            # # Overview
            #
            # The `Status` message contains three pieces of data: error code, error message,
            # and error details. The error code should be an enum value of
            # google.rpc.Code, but it may accept additional error codes if needed.  The
            # error message should be a developer-facing English message that helps
            # developers *understand* and *resolve* the error. If a localized user-facing
            # error message is needed, put the localized message in the error details or
            # localize it in the client. The optional error details may contain arbitrary
            # information about the error. There is a predefined set of error detail types
            # in the package `google.rpc` that can be used for common error conditions.
            #
            # # Language mapping
            #
            # The `Status` message is the logical representation of the error model, but it
            # is not necessarily the actual wire format. When the `Status` message is
            # exposed in different client libraries and different wire protocols, it can be
            # mapped differently. For example, it will likely be mapped to some exceptions
            # in Java, but more likely mapped to some error codes in C.
            #
            # # Other uses
            #
            # The error model and the `Status` message can be used in a variety of
            # environments, either with or without APIs, to provide a
            # consistent developer experience across different environments.
            #
            # Example uses of this error model include:
            #
            # - Partial errors. If a service needs to return partial errors to the client,
            #     it may embed the `Status` in the normal response to indicate the partial
            #     errors.
            #
            # - Workflow errors. A typical workflow has multiple steps. Each step may
            #     have a `Status` message for error reporting.
            #
            # - Batch operations. If a client uses batch request and batch response, the
            #     `Status` message should be used directly inside batch response, one for
            #     each error sub-response.
            #
            # - Asynchronous operations. If an API call embeds asynchronous operation
            #     results in its response, the status of those operations should be
            #     represented directly using the `Status` message.
            #
            # - Logging. If some API errors are stored in logs, the message `Status` could
            #     be used directly after any stripping needed for security/privacy reasons.
          "message": "A String", # A developer-facing error message, which should be in English. Any
              # user-facing error message should be localized and sent in the
              # google.rpc.Status.details field, or localized by the client.
          "code": 42, # The status code, which should be an enum value of google.rpc.Code.
          "details": [ # A list of messages that carry the error details.  There will be a
              # common set of message types for APIs to use.
            {
              "a_key": "", # Properties of the object. Contains field @type with type URL.
            },
          ],
        },
        "done": True or False, # If the value is `false`, it means the operation is still in progress.
            # If true, the operation is completed, and either `error` or `response` is
            # available.
        "response": { # If importing ReadGroupSets, an ImportReadGroupSetsResponse is returned. If importing Variants, an ImportVariantsResponse is returned. For pipelines and exports, an empty response is returned.
          "a_key": "", # Properties of the object. Contains field @type with type URL.
        },
        "name": "A String", # The server-assigned name, which is only unique within the same service that originally returns it. For example: `operations/CJHU7Oi_ChDrveSpBRjfuL-qzoWAgEw`
      }

`list(name, pageSize=None, filter=None, pageToken=None, x__xgafv=None)`

    Lists operations that match the specified filter in the request.

    Args:
      name: string, The name of the operation's parent resource. (required)
      pageSize: integer, The maximum number of results to return. If unspecified, defaults to
    256. The maximum value is 2048.
      filter: string, A string for filtering Operations.
    The following filter fields are supported:

    * projectId: Required. Corresponds to
      OperationMetadata.projectId.
    * createTime: The time this job was created, in seconds from the
      [epoch](http://en.wikipedia.org/wiki/Unix_time). Can use `>=` and/or `<=`
      operators.
    * status: Can be `RUNNING`, `SUCCESS`, `FAILURE`, or `CANCELED`. Only
      one status may be specified.
    * labels.key where key is a label key.

    Examples:

    * `projectId = my-project AND createTime >= 1432140000`
    * `projectId = my-project AND createTime >= 1432140000 AND createTime <= 1432150000 AND status = RUNNING`
    * `projectId = my-project AND labels.color = *`
    * `projectId = my-project AND labels.color = red`
      pageToken: string, The standard list page token.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    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.
