Class InjectionPointLazyFxControllerAndViewResolver

java.lang.Object

net.rgielen.fxweaver.spring.InjectionPointLazyFxControllerAndViewResolver

public class InjectionPointLazyFxControllerAndViewResolver
extends Object

This class helps to create a generic FxControllerAndView bean factory that can be used for direct injection of FxControllerAndView instances into Spring components, based on generic type inspection.

To use, define a FxControllerAndView bean factory method like shown below. It is absolutely crucial to define it in prototype scope, since every injection point has to be investigated for its declared generic types!

 @Bean
 public InjectionPointLazyFxControllerAndViewResolver controllerAndViewResolver(FxWeaver fxWeaver) {
     return new InjectionPointLazyFxControllerAndViewResolver(fxWeaver);
 }

 @Bean
 @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
 public  FxControllerAndView controllerAndView(
         InjectionPointLazyFxControllerAndViewResolver controllerAndViewResolver,
         InjectionPoint injectionPoint) {
     return controllerAndViewResolver.resolve(injectionPoint);
 }
 

Based on this configuration, a LazyFxControllerAndView instance can be injected directly into a component:

 @Component
 class ArbitraryComponent {

     private final FxControllerAndView<SomeController, VBox> someController;

     public ArbitraryComponent(FxControllerAndView<SomeController, VBox> someController) {
         this.someController = someController;
     }
 }

Method Detail

resolve

public <C,V extends javafx.scene.Node> FxControllerAndView<C,V> resolve(org.springframework.beans.factory.InjectionPoint injectionPoint)
