Method Details

getEventType

public InstanceLifecycleEventType getEventType()

Description copied from interface: InstanceLifecycleEvent

Gets the type of event this describes. The values may be:

• PRE_PRODUCTION
• POST_PRODUCTION
• PRE_DESTRUCTION

Specified by:

getEventType in interface InstanceLifecycleEvent

Returns:

The type of event being described

getActiveDescriptor

public ActiveDescriptor<?> getActiveDescriptor()

Description copied from interface: InstanceLifecycleEvent

The active descriptor that is being used for the operation. For PRE_PRODUCTION and POST_PRODUCTION this is the descriptor that will create or that created the object. For PRE_DESTRUCTION this is the descriptor that will be used to destroy the object

Specified by:

getActiveDescriptor in interface InstanceLifecycleEvent

Returns:

The descriptor associated with this event

getLifecycleObject

public Object getLifecycleObject()

Description copied from interface: InstanceLifecycleEvent

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. Will be null in the PRE_PRODUCTION case

Specified by:

getLifecycleObject in interface InstanceLifecycleEvent

Returns:

The object that was produced or will be destroyed. Will be null in the PRE_PRODUCTION case

getKnownInjectees

public Map<Injectee,Object> getKnownInjectees()

Description copied from interface: InstanceLifecycleEvent

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 PRE_PRODUCTION and POST_PRODUCTION cases this will return non-null if the system knows the objects that will be or were injected into the produced object. If this method returns null in the PRE_PRODUCTION or 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-party (pre-reified) ActiveDescriptors. If this method returns an empty map then the system knows that nothing will be or was injected into to produced object.

Specified by:

getKnownInjectees in interface InstanceLifecycleEvent

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.

toString

public String toString()

Overrides:

toString in class Object
