public class AttributeList extends ArrayList<Object>

Represents a list of values for attributes of an MBean. See the getAttributes and setAttributes methods of MBeanServer and MBeanServerConnection.

It is not permitted to add objects to an AttributeList that are not instances of Attribute. This will produce an IllegalArgumentException when calling methods in this class, or when using listIterator and add or set.
