ProcessInjectionTarget

Type Parameters:

X - The managed bean class, session bean class or Jakarta EE component class supporting injection
```
public interface ProcessInjectionTarget<X>
```
The container fires an event of this type for every Jakarta EE component class supporting injection that may be instantiated by the container at runtime, including every managed bean declared using javax.annotation.ManagedBean, Jakarta Enterprise Bean 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 Jakarta 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.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`addDefinitionError(java.lang.Throwable t)` Registers a definition error with the container, causing the container to abort deployment after bean discovery is complete.
`AnnotatedType<X>`	`getAnnotatedType()` Returns the `AnnotatedType` representing the managed bean class, session bean class or other Jakarta EE component class supporting injection.
`InjectionTarget<X>`	`getInjectionTarget()` Returns the `InjectionTarget` object that will be used by the container to perform injection.
`void`	`setInjectionTarget(InjectionTarget<X> injectionTarget)` Replaces the `InjectionTarget` which performs injection for this target.

AnnotatedType<X> getAnnotatedType()
```
    Returns the AnnotatedType representing the managed bean class, session bean class or other Jakarta 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
  - getInjectionTarget
```
InjectionTarget<X> getInjectionTarget()
```
    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
  - setInjectionTarget
```
void setInjectionTarget(InjectionTarget<X> injectionTarget)
```
    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
  - addDefinitionError
```
void addDefinitionError(java.lang.Throwable t)
```
    Registers a definition error with the container, causing the container to abort deployment after bean discovery is complete.
    
    Parameters:
    
    t - A Throwable representing the definition error
    
    Throws:
    
    java.lang.IllegalStateException - if called outside of the observer method invocation
