### Method Details

`create(parent, body=None, x__xgafv=None)`

    Create an Access Level. The longrunning
    operation from this RPC will have a successful status once the Access
    Level has
    propagated to long-lasting storage. Access Levels containing
    errors will result in an error response for the first error encountered.

    Args:
      parent: string, Required. Resource name for the access policy which owns this Access
    Level.

    Format: `accessPolicies/{policy_id}` (required)
      body: object, The request body.
        The object takes the form of:

`list_next(previous_request, previous_response)`

    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.

`patch(name, body=None, updateMask=None, x__xgafv=None)`

    Update an Access Level. The longrunning
    operation from this RPC will have a successful status once the changes to
    the Access Level have propagated
    to long-lasting storage. Access Levels containing
    errors will result in an error response for the first error encountered.

    Args:
      name: string, Required. Resource name for the Access Level. The `short_name` component
    must begin with a letter and only include alphanumeric and '_'. Format:
    `accessPolicies/{policy_id}/accessLevels/{short_name}`. The maximum length
     // of the `short_name` component is 50 characters. (required)
      body: object, The request body.
        The object takes the form of:
