| * 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: <code>pre-resolve pre-resolve-dependency post-download</code> |
| * </p> |
| * <p> |
| * 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: <code>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)</code> |
