Annotation Interface OnDelete

@Target({METHOD,FIELD,TYPE})@Retention(RUNTIME)public @interfaceOnDelete
Specifies anon delete action for a foreign key constraint. The most common usage is@OnDelete(action = CASCADE). Note that this results in anon delete cascade clause in the DDL definition of the foreign key. It's completely different toCascadeType.REMOVE.

Like database triggers,on delete actions can cause state held in memory to lose synchronization with the database.
