Examples of javax.management.Attribute

javax.management.Attribute
A representation of an MBean attribute. It is a pair, a {@link #getName() Name} and a {@link #getValue() Value}.
An Attribute is returned by a getter operation or passed to a a setter operation. @author Juha Lindfors. @author Adrian Brock. @version $Revision: 1.4 $

- Overrode hashCode() to return same hash for objects that are equal
- Removed 'instanceof' from equals() as it tends to break the symmetricity requirement when subclasses are involved
