Class ApplicationScopedBeanInterceptorHandler

java.lang.Object

org.apache.webbeans.intercept.NormalScopedBeanInterceptorHandler

org.apache.webbeans.intercept.ApplicationScopedBeanInterceptorHandler

All Implemented Interfaces:

Serializable, javax.inject.Provider

public class ApplicationScopedBeanInterceptorHandler
extends NormalScopedBeanInterceptorHandler

This is a Provider especially made for @ApplicationScoped beans.

Since there is only one single contextual instance of an @ApplicationScoped bean, we can simply cache this instance inside our bean. We only need to reload this instance if it is null. This happens at the first usage and after the MethodHandler got deserialized

Also if the application uses the AlterableContext.destroy(javax.enterprise.context.spi.Contextual) method on any ApplicationScoped bean, then the standard NormalScopedBeanInterceptorHandler must be configured to prevent any caching. Be careful as this might slow down your application!
