public interface QueryExp extends Serializable
Represents relational constraints similar to database query "where clauses". Instances of QueryExp are returned by the static methods of the
Queryclass.It is possible, but not recommended, to create custom queries by implementing this interface. In that case, it is better to extend the
QueryEvalclass than to implement the interface directly, so that thesetMBeanServer(javax.management.MBeanServer)method works correctly.- Since:

Method Detail
apply
boolean apply(ObjectName name) throws BadStringOperationException, BadBinaryOpValueExpException, BadAttributeValueExpException, InvalidApplicationException
Applies the QueryExp on an MBean.- Parameters:
name- The name of the MBean on which the QueryExp will be applied.- Returns:
- True if the query was successfully applied to the MBean, false otherwise
- Throws:
BadStringOperationException- when an invalid string operation is passed to a method for constructing a queryBadBinaryOpValueExpException- when an invalid expression is passed to a method for constructing a queryBadAttributeValueExpException- when an invalid MBean attribute is passed to a query constructing methodInvalidApplicationException- when an invalid apply is attempted
setMBeanServer
void setMBeanServer(MBeanServer s)
Sets the MBean server on which the query is to be performed.- Parameters:
s- The MBean server on which the query is to be performed.
