Method Detail

manageObject

void manageObject(Object managedObject)
                  throws Exception

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

Parameters:

managedObject - the managed object

Throws:

Exception - can be thrown if the object could not be added

manageNamedObject

void manageNamedObject(Object managedObject,
                     Object preferredName)
                       throws Exception

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

Parameters:

managedObject - the managed object

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

Throws:

Exception - can be thrown if the object could not be added

getManagedObjectName

<T> T getManagedObjectName(Object managedObject,
                         String customName,
                         Class<T> nameType)
                       throws Exception

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

Parameters:

managedObject - 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:

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

unmanageObject

void unmanageObject(Object managedObject)
                    throws Exception

Removes the managed object.

Parameters:

managedObject - the managed object

Throws:

Exception - can be thrown if the object could not be removed

unmanageNamedObject

void unmanageNamedObject(Object name)
                         throws Exception

Removes a managed object by name.

Parameters:

name - an object name previously created by this strategy.

Throws:

Exception - can be thrown if the object could not be removed

isManaged

boolean isManaged(Object managedObject,
                Object name)

Determines if an object or name is managed.

Parameters:

managedObject - the object to consider

name - the name to consider

Returns:

true if the given object or name is managed

notify

void notify(EventObject event)
            throws Exception

Management events provide a single model for capturing information about execution points in the application code. Management strategy implementations decide if and where to record these events. Applications communicate events to management strategy implementations via the notify(EventObject) method.

Parameters:

event - the event

Throws:

Exception - can be thrown if the notification failed

getEventNotifiers

List<EventNotifier> getEventNotifiers()

Gets the event notifiers.

Returns:

event notifiers

setEventNotifiers

void setEventNotifiers(List<EventNotifier> eventNotifier)

Sets the list of event notifier to use.

Parameters:

eventNotifier - list of event notifiers

addEventNotifier

void addEventNotifier(EventNotifier eventNotifier)

Adds the event notifier to use.

Ensure the event notifier has been started if its a Service, as otherwise it would not be used.

Parameters:

eventNotifier - event notifier

removeEventNotifier

boolean removeEventNotifier(EventNotifier eventNotifier)

Removes the event notifier

Parameters:

eventNotifier - event notifier to remove

Returns:

true if removed, false if already removed

getEventFactory

Gets the event factory

Returns:

event factory

setEventFactory

void setEventFactory(EventFactory eventFactory)

Sets the event factory to use
