Represents relational constraints similar to database query "where clauses". Instances of QueryExp are returned by the static methods of the Query class.
It is possible, but not recommended, to create custom queries by implementing this interface. In that case, it is better to extend the QueryEval class than to implement the interface directly, so that the setMBeanServer method works correctly.
