Constant Field Values

serviceItem

private volatile Object serviceItem

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

servID

private transient ServiceID servID

The service ID of the serviceItem 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).

Constructor Detail

RegistrarEvent

public RegistrarEvent(Object source,
                      long eventID,
                      long seqNo,
                      MarshalledObject handback,
                      ServiceID serviceID,
                      int transition,
                      Item item)

Simple constructor.

Parameters:

source - the ServiceRegistrar that generated the event

eventID - the registration eventID

seqNo - the sequence number of this event

handback - the client handback

serviceID - the serviceID of the serviceItem that triggered the event

transition - the transition that triggered the event

item - the new state of the serviceItem, or null if deleted

Method Detail

getServiceItem

public ServiceItem getServiceItem()

Returns the new state of the serviceItem, or null if the serviceItem was deleted from the lookup service.

Specified by:

getServiceItem in class ServiceEvent

Returns:

a ServiceItem object representing the service item value

getServiceID

public ServiceID getServiceID()

Description copied from class: ServiceEvent

Returns the serviceID of the item that triggered the event.

Overrides:

getServiceID in class ServiceEvent

Returns:

a ServiceID object representing the service ID value

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException

Writes the default serializable field value for this instance, followed by the serviceItem's service ID encoded as specified by the ServiceID.writeBytes method.

Throws:

IOException

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

Reads the default serializable field value for this instance, followed by the serviceItem's service ID encoded as specified by the ServiceID.writeBytes method. If the value of the serviceItem field is an Item instance, converts it to a ServiceItem.

Throws:

IOException

ClassNotFoundException
