Class ConfigurationEvent

  • public class ConfigurationEvent
extends java.lang.Object
    A Configuration Event.

    ConfigurationEvent objects are delivered to all registered ConfigurationListener service objects. ConfigurationEvents must be delivered in chronological order with respect to each listener.

    A type code is used to identify the type of event. The following event types are defined:

    Additional event types may be defined in the future.

    Security Considerations. ConfigurationEvent objects do not provide Configuration objects, so no sensitive configuration information is available from the event. If the listener wants to locate the Configuration object for the specified pid, it must use ConfigurationAdmin.
