public interface QueryExp extends Serializable
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(javax.management.MBeanServer)
method works correctly.
