      • newObject

        public static Object newObject​(String className)
        Constructs a new object for the given class name. The construction takes no arguments. If an exception occurs during construction, null is returned. All exceptions are written to the Log instance for this class.
        Parameters:
        className - String
        Returns:
        Object
      • newObject

        public static Object newObject​(String className,

                                       Object[] args)
        Constructs a new object for the given class name and with the given arguments. The arguments must be specified in terms of their Class[] types and their Object[] values. Example: String s = newObject("java.lang.String", new Class[] { String.class}, new String[] { "test"}); is equivalent to: String s = new String("test"); If an exception occurs during construction, null is returned. All exceptions are written to the Log instance for this class.
