package javax.enterprise.inject.spi;

The container fires an event of this type for every Java EE component class supporting injection that may be instantiated by the container at runtime, including every managed bean declared using javax.annotation.ManagedBean, EJB session or message-driven bean, enabled bean, enabled interceptor or enabled decorator.

Any observer of this event is permitted to wrap and/or replace the InjectionTarget. The container must use the final value of this property, after all observers have been called, whenever it performs injection upon the managed bean, session bean or other Java EE component class supporting injection.

For example, this observer decorates the InjectionTarget for all servlets.

 public <T extends Servlet> void decorateServlet(@Observes ProcessInjectionTarget<T> pit) {
     pit.setInjectionTarget(decorate(pit.getInjectionTarget()));
 }
 

If any observer method of a ProcessInjectionTarget event throws an exception, the exception is treated as a definition error by the container.

Parameters:
<X> The managed bean class, session bean class or Java EE component class supporting injection
Author(s):
David Allen

InjectionTarget
public interface ProcessInjectionTarget<X> {
    
Returns the AnnotatedType representing the managed bean class, session bean class or other Java EE component class supporting injection.

Returns:
the AnnotatedType of the bean with an injection target
Throws:
java.lang.IllegalStateException if called outside of the observer method invocation
    public AnnotatedType<X> getAnnotatedType();

    
Returns the InjectionTarget object that will be used by the container to perform injection.

Returns:
the InjectionTarget object which performs the injection
Throws:
java.lang.IllegalStateException if called outside of the observer method invocation
    public InjectionTarget<X> getInjectionTarget();

    
Replaces the InjectionTarget which performs injection for this target.

Parameters:
injectionTarget The new InjectionTarget to use
Throws:
java.lang.IllegalStateException if called outside of the observer method invocation
    public void setInjectionTarget(InjectionTarget<X> injectionTarget);

    
Registers a definition error with the container, causing the container to abort deployment after bean discovery is complete.

Parameters:
t A java.lang.Throwable representing the definition error
Throws:
java.lang.IllegalStateException if called outside of the observer method invocation
    public void addDefinitionError(Throwable t);
