Interface QueryExp

public interface QueryExp extends Serializable

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

Since: 1.5

Method Summary
boolean	apply(ObjectName name) Applies the query to the specified management bean.
void	setMBeanServer(MBeanServer server) Changes the {@link MBeanServer} on which this query is performed.
