Class ConfigurationEvent

java.lang.Object
  org.osgi.service.cm.ConfigurationEvent

public class ConfigurationEvent

extends java.lang.Object

A Configuration Event.

ConfigurationEvent objects are delivered to all registered ConfigurationListener service objects. ConfigurationEvents must be asynchronously 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:

• CM_UPDATED
• CM_DELETED

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.

Since:

1.2
