Interface IInitializer

All Known Implementing Classes:
DebugBarInitializer, Initializer, Initializer, Initializer, Initializer, UploadProgressBar.ComponentInitializer
public interface IInitializer
Initializes something when application loads.

Initializer can be used for clustering. Lets say you access a page that has a link to a resource on node A now the url for the resource gets forwarded to node B, but node B doesn't have the resource registered yet because maybe the page class hasn't been loaded and so its static block hasn't run yet. So the initializer is a place for you to register all those resources and do all the stuff you used to do in the static blocks.

You don't have to pre-register package resources, as they can be initialized lazily.

Initializers can be configured via ServiceLoader, i.e. by having a file /META-INF/services/org.apache.wicket.IInitializer in the class path root, with each line containing the full class name of an IInitializer.
