Interface ManagedLifeCycle

All Superinterfaces:

ManagedPostConstruct, ManagedPreDestroy

All Known Implementing Classes:

AbstractLooper

public interface ManagedLifeCycle
extends ManagedPostConstruct, ManagedPreDestroy

A managed life cycle covers instance creation, post-construction and pre-destroying. Post-construction and pre-destroying are inherited from ManagedPostConstruct, respective ManagedPreDestroy. This interface only adds automatic creation at container start.

To benefit from managed life cycle a class should implement this interface, as in sample code below.

 class DemoClass implements ManagedLifeCycle
 {
  void postConstruct() ...
 
  void preDestroy() ...
 }
 

Managed life cycle interface can be used on class implementation, as in example above or can be extended by class interface, like below:

 class DemoInterface extends ManagedLifeCycle
 {
 }
 
 class DemoClass implements DemoInterface
 {
  void postConstruct() ...
 
  void preDestroy() ...
 }
