Examples of org.apache.commons.configuration2.event.ConfigurationEvent

org.apache.commons.configuration2.convert.DefaultListDelimiterHandler
An event class for reporting updates on a configuration object.

Event objects of this type are used for "raw" events, i.e. unfiltered modifications of any kind. A level with semantically higher events (e.g. for property changes) may be built on top of this fundamental event mechanism.

Each event can contain the following data:
- A source object, which is usually the configuration object that was modified.
- The event's type. This is an object that corresponds to constant declarations in specific event classes. It describes what exactly has happened.
- If available, the name of the property whose modification caused the event.
- If available, the value of the property that caused this event.
- A flag whether this event was generated before or after the update of the source configuration. A modification of a configuration typically causes two events: one event before and one event after the modification is performed. This allows event listeners to react at the correct point of time.
The following standard events are generated by typical configuration implementations (the constants for the event types are defined in this class:

ADD_PROPERTY

This event is triggered for each call of the {@code addProperty()}method of a configuration object. It contains the name of the property, to which new data is added, and the value object that is added to this property (this may be an array or a list if multiple values are added).

SET_PROPERTY

Calling the {@code setProperty()} method triggers this event. Theevent object stores the name of the affected property and its new value.

CLEAR_PROPERTY

If a property is removed from a configuration (by calling the {@code clearProperty()} method), an event of this type is fired. Inthis case the event object only stores the name of the removed property, the value is null.

CLEAR

This event is fired when the whole configuration is cleared. The corresponding event object contains no additional data.
