createManagedObject

public <T> T createManagedObject(Class<T> clazz)

Create a managed object for the given class. The object will be injected and any PostConstruct methods will be called. The returned object can be cast to the clazz type but is not necessarily a direct reference to the managed instance. All invocations on the returned object should be on its public methods. It is the responsibility of the caller to destroy the returned object by calling destroyManagedObject(Object managedObject).

Specified by:

createManagedObject in interface InjectionManager

Parameters:

clazz - Class to be instantiated

Returns:

managed object

Throws:

InjectionException

createManagedObject

public <T> T createManagedObject(Class<T> clazz,
                        boolean invokePostConstruct)
                      throws InjectionException

Create a managed object for the given class. The object will be injected and if invokePostConstruct is true, any @PostConstruct methods on the instance's class(and super-classes) will be invoked after injection. The returned object can be cast to the clazz type but is not necessarily a direct reference to the managed instance. All invocations on the returned object should be on its public methods. It is the responsibility of the caller to destroy the returned object by calling destroyManagedObject(Object managedObject).

Specified by:

createManagedObject in interface InjectionManager

Parameters:

clazz - Class to be instantiated

invokePostConstruct - if true, invoke any @PostConstruct methods on the instance's class(and super-classes) after injection.

InjectionException

destroyManagedObject

public void destroyManagedObject(Object managedObject)

                        boolean validate)
                          throws InjectionException

Destroy a managed object that was created via createManagedObject. Any PreDestroy methods will be called.

Specified by:

InjectionException

inject

public void inject(Class clazz,

          boolean invokePostConstruct)
            throws InjectionException

Description copied from interface: InjectionManager

Perform injection.

Specified by:

inject in interface InjectionManager

Parameters:

instance - Target instance for injection, or null if injection is class-based. Any error encountered during any portion of injection is propagated immediately.

clazz - The class of the instance to perform injection. This is needed b/c of static injection.

envDescriptor - The descriptor containing the injection information.

componentId - The id of the component in whose jndi environment injection actually occurs. Null indicates the current jndi environment.

invokePostConstruct - if true, invoke any @PostConstruct methods

Throws:

InjectionException
