## Class IvyEvent

- java.lang.Object
- - org.apache.ivy.core.event.IvyEvent

Direct Known Subclasses:
  DownloadEvent, PrepareDownloadEvent, PublishEvent, ResolveDependencyEvent, ResolveEvent, RetrieveArtifactEvent, RetrieveEvent, TransferEvent

    public class IvyEvent
    extends java.lang.Object

The root of all ivy events Any ivy event knows which ivy instance triggered the event (the source) and also has a name and a map of attributes. The name of the event represents the event type, usually there is a one - one mapping between event names and IvyEvent subclass, even if this is not mandatory. Example: pre-resolve pre-resolve-dependency post-download The map of attributes is a Map from String keys to String values. It is especially useful to filter events, and to get some of their essential data in some context where access to Java types is not easy (in an ant build file, for example), Example: pre-resolve (organisation=foo, module=bar, revision=1.0, conf=default) post-download (organisation=foo, module=bar, revision=1.0, artifact=foo-test, type=jar, ext=jar)
