Class DefaultPageInjector

java.lang.Object

to.etc.domui.injector.DefaultPageInjector

All Implemented Interfaces:

IPageInjector

@DefaultNonNull
public final class DefaultPageInjector
extends Object
implements IPageInjector

This is the default DomUI page injector. It is responsible for providing (injecting) values into page setters where required. This default version only accepts the @UIUrlParameter annotation and uses it to inject either URL parameter values or entities loaded from an URL parameter into the page. This can be extended to add extra methods to inject values into a page, for instance using Spring (NO! NO! Use something good instead of this piece of shit!), Guice, Pico/Nanocontainer or whatever.
