manageObject

public void manageObject(java.lang.Object managedObject)
                  throws java.lang.Exception

Description copied from interface: ManagementStrategy

Adds a managed object allowing the ManagementStrategy implementation to record or expose the object as it sees fit.

Specified by:

manageObject in interface ManagementStrategy

Parameters:

managedObject - the managed object

Throws:

java.lang.Exception - can be thrown if the object could not be added

getManagedObjectName

public <T> T getManagedObjectName(java.lang.Object managableObject,
                                  java.lang.String customName,
                                  java.lang.Class<T> nameType)
                       throws java.lang.Exception

Description copied from interface: ManagementStrategy

Construct an object name, where either the object to be managed and/or a custom name component are provided

Specified by:

getManagedObjectName in interface ManagementStrategy

Parameters:

managableObject - the object to be managed

customName - a custom name component

nameType - the name type required

Returns:

an object name of the required type if supported, otherwise null

Throws:

java.lang.Exception - can be thrown if the object name could not be created

manageNamedObject

public void manageNamedObject(java.lang.Object managedObject,
                              java.lang.Object preferedName)
                       throws java.lang.Exception

Description copied from interface: ManagementStrategy

Adds a managed object allowing the ManagementStrategy implementation to record or expose the object as it sees fit.

Specified by:

manageNamedObject in interface ManagementStrategy

Parameters:

managedObject - the managed object

preferedName - representing the preferred name, maybe a String, or a JMX ObjectName

Throws:

java.lang.Exception - can be thrown if the object could not be added

unmanageObject

public void unmanageObject(java.lang.Object managedObject)
                    throws java.lang.Exception

Description copied from interface: ManagementStrategy

Removes the managed object.

Specified by:

unmanageObject in interface ManagementStrategy

Parameters:

managedObject - the managed object

Throws:

java.lang.Exception - can be thrown if the object could not be removed

unmanageNamedObject

public void unmanageNamedObject(java.lang.Object name)
                         throws java.lang.Exception

Description copied from interface: ManagementStrategy

Removes a managed object by name.

Specified by:

unmanageNamedObject in interface ManagementStrategy

Parameters:

name - an object name previously created by this strategy.

Throws:

java.lang.Exception - can be thrown if the object could not be removed

isManaged

public boolean isManaged(java.lang.Object managableObject,
                         java.lang.Object name)

true if the given object or name is managed

notify

public void notify(java.util.EventObject event)
            throws java.lang.Exception

Description copied from interface: ManagementStrategy

Applications communicate events to management strategy implementations via the notify(EventObject) method.

Specified by:

notify in interface ManagementStrategy

Parameters:

event - the event

Throws:

java.lang.Exception - can be thrown if the notification failed
