Interface QueryExp

All Superinterfaces:
Known Implementing Classes:

public interface QueryExp
extends Serializable

Applies the type of relational constraints seen in the where clauses of databases to an ObjectName. Instances of this class are usually returned by the static methods of the Query classes. If a custom implementation is required, it is better to extend the QueryEval class, rather than simply implementing this interface, in order to ensure that the setMBeanServer(MBeanServer) method functions correctly.

Method Summary

apply(ObjectName name)
Applies the query to the specified management bean.
setMBeanServer(MBeanServer server)
Changes the MBeanServer on which this query is performed.
