### Method Details

`aggregatedList(project, filter=None, includeAllScopes=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, serviceProjectNumber=None, x__xgafv=None)`

    Retrieves the list of all VM Extension Policy resources
    available to the specified project.

    To prevent failure, it's recommended that you set the
    `returnPartialSuccess` parameter to `true`.

    Args:
      project: string, Name of the project scoping this request. (required)
      filter: string, A filter expression that filters resources listed in the response. Most
    Compute resources support two types of filter expressions:
    expressions that support regular expressions and expressions that follow
    API improvement proposal AIP-160.
    These two types of filter expressions cannot be mixed in one request.

    If you want to use AIP-160, your expression must specify the field name, an
    operator, and the value that you want to use for filtering. The value
    must be a string, a number, or a boolean. The operator
    must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`.

    For example, if you are filtering Compute Engine instances, you can
    exclude instances named `example-instance` by specifying
    `name != example-instance`.

    The `:*` comparison can be used to test whether a key has been defined.
    For example, to find all objects with `owner` label use:
    ```
    labels.owner:*
    ```

    You can also filter nested fields. For example, you could specify
    `scheduling.automaticRestart = false` to include instances only
    if they are not scheduled for automatic restarts. You can use filtering
    on nested fields to filter based onresource labels.

    To filter on multiple expressions, provide each separate expression within
    parentheses. For example:
    ```
    (scheduling.automaticRestart = true)
    (cpuPlatform = "Intel Skylake")
    ```
    By default, each expression is an `AND` expression. However, you
    can include `AND` and `OR` expressions explicitly.
    For example:
    ```
    (cpuPlatform = "Intel Skylake") OR
    (cpuPlatform = "Intel Broadwell") AND
    (scheduling.automaticRestart = true)
    ```

    If you want to use a regular expression, use the `eq` (equal) or `ne`
    (not equal) operator against a single un-parenthesized expression with or
    without quotes or against multiple parenthesized expressions. Examples:

    `fieldname eq unquoted literal`
    `fieldname eq 'single quoted literal'`
    `fieldname eq "double quoted literal"`
    `(fieldname1 eq literal) (fieldname2 ne "literal")`

    The literal value is interpreted as a regular expression using GoogleRE2 library syntax.
    The literal value must match the entire field.

    For example, to filter for instances that do not end with name "instance",
    you would use `name ne .*instance`.

    You cannot combine constraints on multiple fields using regular
    expressions.
      includeAllScopes: boolean, Indicates whether every visible scope for each scope type (zone, region,
    global) should be included in the response. For new resource types added
    after this field, the flag has no effect as new resource types will always
    include every visible scope for each scope type in response. For resource
    types which predate this field, if this flag is omitted or false, only
    scopes of the scope types where the resource type is expected to be found
    will be included.
      maxResults: integer, The maximum number of results per page that should be returned.
    If the number of available results is larger than `maxResults`,
    Compute Engine returns a `nextPageToken` that can be used to get
    the next page of results in subsequent list requests. Acceptable values are
    `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results
    are returned in alphanumerical order based on the resource name.

    You can also sort results in descending order based on the creation
    timestamp using `orderBy="creationTimestamp desc"`. This sorts
    results based on the `creationTimestamp` field in
    reverse chronological order (newest result first). Use this to sort
    resources like operations so that the newest operation is returned first.

    Currently, only sorting by `name` or
    `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the
    `nextPageToken` returned by a previous list request to get
    the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case
    of failure. The default value is false.

    For example, when partial success behavior is enabled, aggregatedList for a
    single zone scope either returns all resources in the zone or no resources,
    with an error code.
      serviceProjectNumber: string, The Shared VPC service project id or service project number for which
    aggregated list request is invoked for subnetworks list-usable api.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

`aggregatedList_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.

`close()`

    Close httplib2 connections.

`delete(project, globalVmExtensionPolicy, body=None, requestId=None, x__xgafv=None)`

    Purge scoped resources (zonal policies) from a global VM extension
    policy, and then delete the global VM extension policy. Purge of the scoped
    resources is a pre-condition of the global VM extension policy deletion.
    The deletion of the global VM extension policy happens after the purge
    rollout is done, so it's not a part of the LRO. It's an automatic process
    that triggers in the backend.

    Args:
      project: string, Project ID for this request. (required)
      globalVmExtensionPolicy: string, Name of the global VM extension policy to purge scoped resources for. (required)
      body: object, The request body.
        The object takes the form of:

    {
      "conflictBehavior": "A String", # Optional. Specifies the behavior of the rollout if a conflict is detected in a
          # project during a rollout. This only applies to `insert` and `update`
          # methods.
          #
          # A conflict occurs in the following cases:
          # * `insert` method: If the zonal policy already exists when the insert
          #   happens.
          # * `update` method: If the zonal policy was modified by a zonal API call
          #   outside of this rollout.
          #
          # Possible values are the following:
          # * `""` (empty string): If a conflict occurs, the local value is not
          #   overwritten. This is the default behavior.
          # * `"overwrite"`: If a conflict occurs, the local value is overwritten
          #   with the rollout value.
      "name": "A String", # Optional. The name of the rollout plan.
          # Ex.
          # projects//locations/global/rolloutPlans/.
      "predefinedRolloutPlan": "A String", # Optional. Predefined rollout plan.
      "retryUuid": "A String", # Optional. The UUID that identifies a policy rollout retry attempt for update and
          # delete operations. Set this field only when retrying a rollout for an
          # existing extension policy.
          #
          # * `update` method: Lets you retry policy rollout without changes.
          # An error occurs if you set retry_uuid but the policy is modified.
          # * `delete` method: Lets you retry policy deletion rollout if the
          # previous deletion rollout is not finished and the policy is in the
          # DELETING state. If you set this field when the policy is not in the
          # DELETING state, an error occurs.
    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so
    that if you must retry your request, the server will know to ignore the
    request if it has already been completed.

    For example, consider a situation where you make an initial request and
    the request times out. If you make the request again with the same
    request ID, the server can check if original operation with the same
    request ID was received, and if so, will ignore the second request. This
    prevents clients from accidentally creating duplicate commitments.

    The request ID must be
    a valid UUID with the exception that zero UUID is not supported
    (00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

    }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so
    that if you must retry your request, the server will know to ignore the
    request if it has already been completed.

    For example, consider a situation where you make an initial request and
    the request times out. If you make the request again with the same
    request ID, the server can check if original operation with the same
    request ID was received, and if so, will ignore the second request. This
    prevents clients from accidentally creating duplicate commitments.

    The request ID must be
    a valid UUID with the exception that zero UUID is not supported
    (00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`list(project, filter=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Lists global VM extension policies.

    Args:
      project: string, Project ID for this request. (required)
      filter: string, A filter expression that filters resources listed in the response. Most
    Compute resources support two types of filter expressions:
    expressions that support regular expressions and expressions that follow
    API improvement proposal AIP-160.
    These two types of filter expressions cannot be mixed in one request.

    If you want to use AIP-160, your expression must specify the field name, an
    operator, and the value that you want to use for filtering. The value
    must be a string, a number, or a boolean. The operator
    must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`.

    For example, if you are filtering Compute Engine instances, you can
    exclude instances named `example-instance` by specifying
    `name != example-instance`.

    The `:*` comparison can be used to test whether a key has been defined.
    For example, to find all objects with `owner` label use:
    ```
    labels.owner:*
    ```

    You can also filter nested fields. For example, you could specify
    `scheduling.automaticRestart = false` to include instances only
    if they are not scheduled for automatic restarts. You can use filtering
    on nested fields to filter based onresource labels.

    To filter on multiple expressions, provide each separate expression within
    parentheses. For example:
    ```
    (scheduling.automaticRestart = true)
    (cpuPlatform = "Intel Skylake")
    ```
    By default, each expression is an `AND` expression. However, you
    can include `AND` and `OR` expressions explicitly.
    For example:
    ```
    (cpuPlatform = "Intel Skylake") OR
    (cpuPlatform = "Intel Broadwell") AND
    (scheduling.automaticRestart = true)
    ```

    If you want to use a regular expression, use the `eq` (equal) or `ne`
    (not equal) operator against a single un-parenthesized expression with or
    without quotes or against multiple parenthesized expressions. Examples:

    `fieldname eq unquoted literal`
    `fieldname eq 'single quoted literal'`
    `fieldname eq "double quoted literal"`
    `(fieldname1 eq literal) (fieldname2 ne "literal")`

    The literal value is interpreted as a regular expression using GoogleRE2 library syntax.
    The literal value must match the entire field.

    For example, to filter for instances that do not end with name "instance",
    you would use `name ne .*instance`.

    You cannot combine constraints on multiple fields using regular
    expressions.
      maxResults: integer, The maximum number of results per page that should be returned.
    If the number of available results is larger than `maxResults`,
    Compute Engine returns a `nextPageToken` that can be used to get
    the next page of results in subsequent list requests. Acceptable values are
    `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results
    are returned in alphanumerical order based on the resource name.

    You can also sort results in descending order based on the creation
    timestamp using `orderBy="creationTimestamp desc"`. This sorts
    results based on the `creationTimestamp` field in
    reverse chronological order (newest result first). Use this to sort
    resources like operations so that the newest operation is returned first.

    Currently, only sorting by `name` or
    `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the
    `nextPageToken` returned by a previous list request to get
    the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case
    of failure. The default value is false.

    For example, when partial success behavior is enabled, aggregatedList for a
    single zone scope either returns all resources in the zone or no resources,
    with an error code.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so
    that if you must retry your request, the server will know to ignore the
    request if it has already been completed.

    For example, consider a situation where you make an initial request and
    the request times out. If you make the request again with the same
    request ID, the server can check if original operation with the same
    request ID was received, and if so, will ignore the second request. This
    prevents clients from accidentally creating duplicate commitments.

    The request ID must be
    a valid UUID with the exception that zero UUID is not supported
    (00000000-0000-0000-0000-000000000000).
      x__xgafv: string, V1 error format.
        Allowed values
