As packing shapes is always a problem with a high complexity I needed to come up with a solution that is also fast. The desired layout was inspired by Wordle, but as Wordle is unfortunately closed source I needed to build the algorithm myself. text/html 2011-12-01T12:07:24+01:00 shox http://www.dontdrinkandroot.net/java/wicket/models?rev=1322737644&do=diff Introduction While Models are one of the fundamental concepts in Wicket the details are hard to understand if you are new to the framework. Models are a level of abstraction between a component and the data this component uses. This is necessary as Wicket persists its components and it is not always desirable that the whole dataobject is persisted as well. Even more complex operations such as transformations can be performed. A clever use of Models can significantly reduce the space used by th… text/html 2011-11-22T16:09:26+01:00 shox http://www.dontdrinkandroot.net/java/wicket/models/examples?rev=1321974566&do=diff Loadable Detachable DB Entity Model Assume our entity implements a Long getId() method for the primary key and we have a corresponding DAO. public class LoadableDetachableEntityModel extends LoadableDetachableModel<Entity> { @SpringBean private EntityDao entityDao; private Long id; public LoadableDetachableEntityModel(Long id) { super(); this.id = id; this.inject(); } public LoadableDetachableEntityModel(Entity entity) { super(…
