Field Detail

item

protected Object item

The new state of the item, or null if the item has been deleted from the lookup service. This is either a ServiceItem or an Item (to be converted to a ServiceItem when unmarshalled).

servID

protected transient ServiceID servID

The service ID of the item that triggered the event. This field is used instead of the inherited serviceID field (which is set to null) and is written directly as a 128-bit value in order to avoid potential codebase annotation loss (see bug 4745728).
