Represents relational constraints that can be used in 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(MBeanServer) method works correctly.
