Interface javax.infobus.InfoBusPolicyHelper

public interface InfoBusPolicyHelper

canAddDataConsumer(InfoBus, InfoBusDataConsumer)

Determines if the specifed InfoBus's canAddDataConsumer method can be executed, and throws a runtime Exception if not.

canAddDataController(InfoBus, InfoBusDataController, int)

Determines if the specifed InfoBus's canAddDataController method can be executed, and throws a runtime Exception if not.

canAddDataProducer(InfoBus, InfoBusDataProducer)

Determines if the specifed InfoBus's canAddDataProducer method can be executed, and throws a runtime Exception if not.

canFireItemAvailable(InfoBus, String, InfoBusDataProducer)

Determines if the specifed InfoBus's canFireItemAvailable method can be executed, and throws a runtime Exception if not.

canFireItemRevoked(InfoBus, String, InfoBusDataProducer)

Determines if the specifed InfoBus's canFireItemRevoked method can be executed, and throws a runtime Exception if not.

canGet(String)

Determines if the static InfoBus open method can be executed, and throws a runtime Exception if not.

canJoin(InfoBus, InfoBusMember)

Determines if the specifed InfoBus's join method can be executed, and throws a runtime Exception if not.

canPropertyChange(InfoBus, PropertyChangeEvent)

Determines if the specifed InfoBus's proprtyChange method can be executed, and throws a runtime Exception if not.

canRegister(InfoBus, InfoBusMember)

Determines if the specifed InfoBus's register method can be executed, and throws a runtime Exception if not.

canRequestItem(InfoBus, String, InfoBusDataConsumer)

Determines if the specifed InfoBus's canRequestItem method can be executed, and throws a runtime Exception if not.

generateDefaultName(Object)

Generates a default InfoBus name from the given object.

 public abstract String generateDefaultName(Object object)

Generates a default InfoBus name from the given object. Ideally the default name should be shared by different objects that occupy a common design space -- e.g., different applets on a shared web page. A default name based on DocBase in AppletContext is an example of one which suits this purpose.

 public abstract void canGet(String busName)

Determines if the static InfoBus open method can be executed, and throws a runtime Exception if not.

 public abstract void canJoin(InfoBus infobus,
                              InfoBusMember member)

Determines if the specifed InfoBus's join method can be executed, and throws a runtime Exception if not.

 public abstract void canRegister(InfoBus infobus,
                                  InfoBusMember member)

 public abstract void canPropertyChange(InfoBus infobus,
                                        PropertyChangeEvent event)

Determines if the specifed InfoBus's proprtyChange method can be executed, and throws a runtime Exception if not.

 public abstract void canAddDataController(InfoBus infobus,
                                           InfoBusDataController controller,
                                           int priority)

Determines if the specifed InfoBus's canAddDataController method can be executed, and throws a runtime Exception if not.

Determines if the specifed InfoBus's canAddDataConsumer method can be executed, and throws a runtime Exception if not.

 public abstract void canFireItemAvailable(InfoBus infobus,
                                           String dataItemName,
