create(project, managedZone, body=None, clientOperationId=None, x__xgafv=None)

Atomically updates the ResourceRecordSet collection.

Args:
  project: string, Identifies the project addressed by this request. (required)
  managedZone: string, Identifies the managed zone addressed by this request. Can be the managed zone name or ID. (required)
  body: object, The request body.
    The object takes the form of:

{ # A Change represents a set of `ResourceRecordSet` additions and deletions applied atomically to a ManagedZone. ResourceRecordSets within a ManagedZone are modified by creating a new Change element in the Changes collection. In turn the Changes collection also records the past modifications to the `ResourceRecordSets` in a `ManagedZone`. The current state of the `ManagedZone` is the sum effect of applying all `Change` elements in the `Changes` collection in sequence.

get(project, managedZone, changeId, clientOperationId=None, x__xgafv=None)

Fetches the representation of an existing Change.

Args:
  project: string, Identifies the project addressed by this request. (required)
  managedZone: string, Identifies the managed zone addressed by this request. Can be the managed zone name or ID. (required)
  changeId: string, The identifier of the requested change, from a previous ResourceRecordSetsChangeResponse. (required)
  clientOperationId: string, For mutating operation requests only. An optional identifier specified by the client. Must be unique for operation resources in the Operations collection.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:

list(project, managedZone, maxResults=None, pageToken=None, sortBy=None, sortOrder=None, x__xgafv=None)

Enumerates Changes to a ResourceRecordSet collection.

Args:
  project: string, Identifies the project addressed by this request. (required)
  managedZone: string, Identifies the managed zone addressed by this request. Can be the managed zone name or ID. (required)
  maxResults: integer, Optional. Maximum number of results to be returned. If unspecified, the server decides how many results to return.
  pageToken: string, Optional. A tag returned by a previous list request that was truncated. Use this parameter to continue a previous list request.
  sortBy: string, Sorting criterion. The only supported value is change sequence.
    Allowed values
      changeSequence - 
  sortOrder: string, Sorting order direction: 'ascending' or 'descending'.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:

When multiple `WrrPolicyItem` objects are configured, the probability of returning an `WrrPolicyItem` object's data is proportional to its weight relative to the sum of weights configured for all items. This weight must be non-negative.

To fetch the results, make another list request and use this value as your page token. This lets you retrieve the complete contents of a very large collection one page at a time. However, if the contents of the collection change between the first and last paginated list request, the set of all elements returned are an inconsistent view of the collection. You can't retrieve a consistent snapshot of a collection larger than the maximum page size.

list_next()

Retrieves the next page of results.

        Args:
          previous_request: The request for the previous page. (required)
          previous_response: The response from the request for the previous page. (required)

        Returns:
          A request object that you can call 'execute()' on to request the next
          page. Returns None if there are no more items in the collection.
