Method Detail

getEventType

InstanceLifecycleEventType getEventType()
Gets the type of even this describes. The values may be:

Returns:
The type of event being described

getActiveDescriptor

ActiveDescriptor<?> getActiveDescriptor()
The active descriptor that is being used for the operation. For POST_PRODUCTION this is the descriptor that created the object. For PRE_DESTRUCTION this is the descriptor that will be used to destroy the object

Returns:
The descriptor associated with this event

getLifecycleObject

Object getLifecycleObject()
The object that is being described by this event. In the POST_PRODUCTION case this is the object that was just produced. In the PRE_DESTRUCTION case this is the object that will be destroyed

Returns:
The object that was produced or will be destroyed

getKnownInjectees

Map<Injectee,Object> getKnownInjectees()
A map from the Injectee to the object actually used in the production, if known. This will return null in the PRE_DESTRUCTION case. In the POST_PRODUCTION case this will return non-null if the system knows the objects that were injected into the produced object. If this method returns null in the POST_PRODUCTION case then the system does not know what objects were injected into the produced object, which happens in the case of objects created by a Factory or objects created by third-parth (pre-reified) ActiveDescriptors. If this method returns an empty map then the system knows that nothing was injected into to produced object.

Returns:
The known map of injection point to injected object, if that information is known. Will be null in the PRE_DESTRUCTION case and in the case where the system does not know the values.
