setMappedObjectName

public void setMappedObjectName(String mappedObjectName)

Set the ObjectName of the single MBean that the encapsulated NotificationFilter will be registered with to listen for Notifications.

Parameters:

mappedObjectName - the ObjectName identifying the target MBean that the encapsulated NotificationFilter is to be registered with

---

setMappedObjectNames

public void setMappedObjectNames(String[] mappedObjectNames)

Set the array of ObjectNames of the MBeans that the encapsulated NotificationFilter will be registered with to listen for Notifications.

Parameters:
