- All Superinterfaces:
Serializable
- All Known Implementing Classes:
ObjectName
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.
