Lifecycle event annotations support
-----------------------------------
Key: CAY-1509
URL: https://issues.apache.org/jira/browse/CAY-1509
Project: Cayenne
Issue Type: Task
Components: Core Library
Affects Versions: 3.1M1
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.1M1
Add annotations for lifecycle events:
@PrePersist, @PostPersist, etc. (all the standard ones, total of 8 annotations)
Each annotated method can process events for preset collection of entity
classes and/or a set of unknown entity classes tagged with a custom annotation.
In the later case a listener is cleanly decoupled from specific entities (this
feature is mixin-inspired). E.g:
@Target(METHOD) @Retention(RUNTIME)
@PrePersist {
Class<? extends Persistent>[] entityTypes();
Class<? extends Annotation>[] entityAnnotations();
}
LifecycleCallbackRegistry API:
/**
* This form of listener registration is very simple and type-safe compared to
other forms available in 3.0 LifecycleCallbackRegistry.
*/
public void addListener(Object annotatedListener);
