Method Detail

apply

public boolean apply(ObjectName name)
              throws BadStringOperationException,
                     BadBinaryOpValueExpException,

Description copied from interface: QueryExp
Apply this query expression to an MBean.

Specified by:
apply in interface QueryExp
Overrides:
apply in class QueryExpSupport

toString

public java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).


setMBeanServer

public void setMBeanServer(MBeanServer server)
Description copied from interface: QueryExp
Set the MBeanServer for this query. Only MBeans registered in this server can be used in queries.

Specified by:
setMBeanServer in interface QueryExp
