Examples of javax.management.AttributeList

javax.management.AttributeList
A list of a MBean attributes.
An AttributeList can be used to get and set multiple MBean attributes in one invocation.
It is an array list that can only contain {@link javax.management.Attribute}s
Note: AttributeLists must be externally synchronized. @see javax.management.Attribute @author Adrian Brock. @version $Revision: 1.2 $
