/**
* <p>Indicates that a method in an MBean class defines an MBean attribute.
* This annotation must be applied to a public method of a public class
* that is itself annotated with an {@link MBean @MBean} or
* {@link MXBean @MXBean} annotation, or inherits such an annotation from
* a superclass.</p>
*
* <p>The annotated method must be a getter or setter. In other words,
* it must look like one of the following...</p>
*
* <pre>
* <i>T</i> get<i>Foo</i>()
* void set<i>Foo</i>(<i>T</i> param)
* </pre>
*
* <p>...where <i>{@code T}</i> is any type and <i>{@code Foo}</i> is the
* name of the attribute. For any attribute <i>{@code Foo}</i>, if only
* a {@code get}<i>{@code Foo}</i> method has a {@code ManagedAttribute}
* annotation, then <i>{@code Foo}</i> is a read-only attribute. If only
* a {@code set}<i>{@code Foo}</i> method has a {@code ManagedAttribute}
* annotation, then <i>{@code Foo}</i> is a write-only attribute. If
* both {@code get}<i>{@code Foo}</i> and {@code set}<i>{@code Foo}</i>
* methods have the annotation, then <i>{@code Foo}</i> is a read-write
* attribute. In this last case, the type <i>{@code T}</i> must be the
* same in both methods.</p>
