Interface IInitializer

All Known Implementing Classes:

Initializer

public interface IInitializer

Initializes something when application loads. Initializer is there 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 by having a /META-INF/wicket/com.example.myapp.properties file in the class path root, with property 'initializer=${initializer class name}'. You can have one such properties per jar file, but the initializer that property denotes can delegate to other initializers of that library.
