QueryExp (Java 2 Platform Ent. Ed. v1.4) - Java Platform, Enterprise Edition v1.4 API Specifications

JavaTM 2 Platform
Ent. Ed. v1.4

javax.management
Interface QueryExp

All Superinterfaces:
Serializable
All Known Implementing Classes:
ObjectName

public interface QueryExp
extends Serializable

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(javax.management.MBeanServer) method works correctly.


Method Summary
 boolean apply(ObjectName name)
          Applies the QueryExp on an MBean.
 void setMBeanServer(MBeanServer s)
          Sets the MBean server on which the query is to be performed.
