Example 1 with TargetBeanInstance

use of org.jboss.weld.bean.proxy.TargetBeanInstance in project core by weld.

the class ProxyClassConstructorInjectionPointWrapper method newInstance.

@Override
protected T newInstance(Object[] parameterValues) {
    // Once the instance is created, a method handler is required regardless of whether
    // an actual bean instance is known yet.

        BeanInstance beanInstance = null;
        if (hasDelegateInjectionPoint()) {
            Object decoratorDelegate = parameterValues[delegateInjectionPointPosition];
            beanInstance = new TargetBeanInstance(decoratorDelegate);
        }
        ProxyFactory.setBeanInstance(contextId, instance, beanInstance, bean);
    } else {
        if (instance instanceof ProxyObject) {
            ((ProxyObject) instance).setHandler(new CombinedInterceptorAndDecoratorStackMethodHandler());
            // Set method handler for private methods if necessary
            InterceptedSubclassFactory.setPrivateMethodHandler(instance);
        }
    }
    return instance;

Example 3 with TargetBeanInstance

Example 4 with TargetBeanInstance

use of org.jboss.weld.bean.proxy.TargetBeanInstance in project core by weld.

the class DecoratorInjectionTarget method inject.

@Override
public void inject(T instance, CreationalContext<T> ctx) {
    super.inject(instance, ctx);
    if (accessibleField != null && instance instanceof DecoratorProxy) {
        // this code is only applicable if the delegate is injected into a field
        // as the proxy can't intercept the delegate when setting the field
        // we need to now read the delegate from the field
        // this is only needed for fields, as constructor and method injection are handed
        // at injection time
        Object delegate;
        try {
            delegate = accessibleField.get(instance);
        } catch (IllegalAccessException e) {

        }
        final ProxyMethodHandler handler = new ProxyMethodHandler(beanManager.getContextId(), new TargetBeanInstance(delegate), getBean());
