### Method Details

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

    ApplyParameters will update current set of Parameters to the set of
    specified nodes of the Memcached Instance.

    Args:
      name: string, Required. Resource name of the Memcached instance for which parameter group updates
    should be applied. (required)
      body: object, The request body.
        The object takes the form of:

    { # Request for ApplyParameters.
        "applyAll": True or False, # Whether to apply instance-level parameter group to all nodes. If set to
            # true, will explicitly restrict users from specifying any nodes, and apply
            # parameter group updates to all nodes within the instance.
        "nodeIds": [ # Nodes to which we should apply the instance-level parameter group.
          "A String",
        ],
      }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`getIamPolicy(resource, options_requestedPolicyVersion=None, x__xgafv=None)`

    Gets the access control policy for a resource.
    Returns an empty policy if the resource exists and does not have a policy
    set.

    Args:
      resource: string, REQUIRED: The resource for which the policy is being requested.
    See the operation documentation for the appropriate value for this field. (required)
      options_requestedPolicyVersion: integer, Optional. The policy format version to be returned.

    Valid values are 0, 1, and 3. Requests specifying an invalid value will be
    rejected.

    Requests for policies with any conditional bindings must specify version 3.
    Policies without any conditional bindings may specify any valid value or
    leave the field unset.

    To learn which resources support conditions in their IAM policies, see the
    [IAM
    documentation](https://cloud.google.com/iam/help/conditions/resource-policies).
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

          # controls for Google Cloud resources.
          #
          #
          # A `Policy` is a collection of `bindings`. A `binding` binds one or more
          # `members` to a single `role`. Members can be user accounts, service accounts,
          # Google groups, and domains (such as G Suite). A `role` is a named list of
          # permissions; each `role` can be an IAM predefined role or a user-created
          # custom role.
          #
          # For some types of Google Cloud resources, a `binding` can also specify a
          # `condition`, which is a logical expression that allows access to a resource
          # only if the expression evaluates to `true`. A condition can add constraints
          # based on attributes of the request, the resource, or both. To learn which
          # resources support conditions in their IAM policies, see the
          # [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

`list(parent, pageToken=None, orderBy=None, pageSize=None, filter=None, x__xgafv=None)`

    Lists Instances in a given project and location.

    Args:
      parent: string, Required. The resource name of the instance location using the form:
        `projects/{project_id}/locations/{location_id}`
    where `location_id` refers to a GCP region (required)

    and a caller should only rely on response's
    next_page_token
    to determine if there are more instances left to be queried.

    my-instance by specifying "name != my-instance".

          #
          # A `Policy` is a collection of `bindings`. A `binding` binds one or more
          # `members` to a single `role`. Members can be user accounts, service accounts,
          # Google groups, and domains (such as G Suite). A `role` is a named list of
          # permissions; each `role` can be an IAM predefined role or a user-created
          # custom role.
          #
          # For some types of Google Cloud resources, a `binding` can also specify a
          # `condition`, which is a logical expression that allows access to a resource
          # only if the expression evaluates to `true`. A condition can add constraints
          # based on attributes of the request, the resource, or both. To learn which
          # resources support conditions in their IAM policies, see the
          # [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

`testIamPermissions(resource, body=None, x__xgafv=None)`

    Returns permissions that a caller has on the specified resource.
    If the resource does not exist, this will return an empty set of
    permissions, not a `NOT_FOUND` error.

    Note: This operation is designed to be used for building permission-aware
    UIs and command-line tools, not for authorization checking. This operation
    may "fail open" without warning.

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

    Updates the defined Memcached Parameters for an existing Instance.
    This method only stages the parameters, it must be followed by
    ApplyParameters to apply the parameters to nodes of the Memcached Instance.

      name: string, Required. Resource name of the Memcached instance for which the parameters should be
    updated. (required)

              # can use this id to determine if the parameters associated with the instance
