<p class="firstline">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.

<p class="firstline">Deletes a long-running operation. It indicates the client is no longer interested in the operation result. It does not cancel the operation.</p>
<p class="toc_element">
<code><a href="#get">get(name, x__xgafv=None)</a></code></p>

<h3>Method Details</h3>
<div class="method">
<code class="details" id="cancel">cancel(name, body, 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 may use Operations.GetOperation or other methods 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 {}.
}</pre>
</div>
<div class="method">
<code class="details" id="delete">delete(name, x__xgafv=None)</code>
<pre>Deletes a long-running operation. It indicates the client is no longer interested in the operation result. It does not cancel the operation.
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 {

}</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 may use this method to poll the operation result at intervals as recommended by the API service.
Args:
name: string, The operation resource name. (required)
x__xgafv: string, V1 error format.
Allowed values
1 - v1 error format
2 - v2 error format
Returns:
An object of the form:
{ # An asynchronous operation in a project that runs over a given cluster. Used to track the progress of a user request that is running asynchronously. Examples include creating a cluster, updating a cluster, and deleting a cluster.
"metadata": { # Service-specific metadata associated 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 programming environments, including REST APIs and RPC APIs. It is used by gRPC (https://github.com/grpc). The error model is designed to be: # The error result of the operation in case of failure.
# Simple to use and understand for most users
# Flexible enough to meet unexpected needsOverviewThe 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 mappingThe 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 usesThe 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.

"details": [ # A list of messages that carry the error details. There will be a common set of message types for APIs to use.

Args:
name: string, The operation collection name. (required)
pageSize: integer, The standard List page size.
filter: string, Required A JSON object that contains filters for the list operation, in the format {"key1":"value1","key2":"value2", ..., }. Possible keys include project_id, cluster_name, and operation_state_matcher.If project_id is set, requests the list of operations that belong to the specified Google Cloud Platform project ID. This key is required.If cluster_name is set, requests the list of operations that were submitted to the specified cluster name.
