How to use

toStringEntries

method

in

alluxio.security.authorization.AccessControlList

 // do not use getX as the name of the method, otherwise it will be used by json serialization
 return (mAcl == null) ? new ArrayList<>() : mAcl.toStringEntries();
}

  * Serialize an AccessControlList object.
  * @param accessControlList the ACL object to be serialized
