* <p>Constructs query object constraints.</p>
*
* <p>The MBean Server can be queried for MBeans that meet a particular
* condition, using its {@link MBeanServer#queryNames queryNames} or
* {@link MBeanServer#queryMBeans queryMBeans} method. The {@link QueryExp}
* parameter to the method can be any implementation of the interface
* {@code QueryExp}, but it is usually best to obtain the {@code QueryExp}
* value by calling the static methods in this class. This is particularly
* true when querying a remote MBean Server: a custom implementation of the
* {@code QueryExp} interface might not be present in the remote MBean Server,
* but the methods in this class return only standard classes that are
* part of the JMX implementation.</p>
*
* <p>As an example, suppose you wanted to find all MBeans where the {@code
* Enabled} attribute is {@code true} and the {@code Owner} attribute is {@code
* "Duke"}. Here is how you could construct the appropriate {@code QueryExp} by
* chaining together method calls:</p>
*
* <pre>
* QueryExp query =
* Query.and(Query.eq(Query.attr("Enabled"), Query.value(true)),
* Query.eq(Query.attr("Owner"), Query.value("Duke")));
* </pre>
