Interface NotificationHandlerRegistry

All Known Subinterfaces:

NotificationHandlerRegistration

public interface NotificationHandlerRegistry

The NotificationHandlerRegistry is used to register and unregister notification handlers. Notification handlers are registered against a PathAddress. The source PathAddress can be a pattern if at least one of its element value is a wildcard (PathElement.getValue() is *). For example:

• /subsystem=messaging/hornetq-server=default/jms-queue=* is an address pattern.
• /subsystem=messaging/hornetq-server=*/jms-queue=* is an address pattern.
• /subsystem=messaging/hornetq-server=default/jms-queue=myQueue is not an address pattern.

Field Details

SERVICE_DESCRIPTOR

static final NullaryServiceDescriptor<NotificationHandlerRegistry> SERVICE_DESCRIPTOR

ANY_ADDRESS

static final PathAddress ANY_ADDRESS

Special path address to register a notification handler for any source. A handler registered with this address will receive all notifications emitted by any source. It is advised to use a suitable NotificationFilter to constrain the received notifications (e.g. by their types).

Method Details

registerNotificationHandler

void registerNotificationHandler(PathAddress source,
 NotificationHandler handler,
 NotificationFilter filter)

Register the given NotificationHandler to receive notifications emitted by the resource at the given source address. The NotificationHandler.handleNotification(Notification) method will only be called on the registered handler if the filter's NotificationFilter.isNotificationEnabled(Notification) returns true for the given notification.

Parameters:

source - the path address of the resource that emit notifications.

handler - the notification handler

filter - the notification filter. Use NotificationFilter.ALL to let the handler always handle notifications

unregisterNotificationHandler

void unregisterNotificationHandler(PathAddress source,
 NotificationHandler handler,
 NotificationFilter filter)

Unregister the given NotificationHandler to stop receiving notifications emitted by the resource at the given source address. The source, handler and filter must match the values that were used during registration to be effectively unregistered.

Parameters:

source - the path address of the resource that emit notifications.

handler - the notification handler

filter - the notification filter
