### Method Details

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

    ApplyParameters will restart the set of specified nodes in order to update them to the current set of parameters for 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",
        ],
