QueryExp (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences.

DETAIL: FIELD | CONSTR | METHOD

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 {@link 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 {@link QueryEval} class than to implement the interface directly, so that the {@link #setMBeanServer} 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.
