Annotation Type Apply

@Target(value=METHOD)
 @Retention(value=RUNTIME)
public @interface Apply

Marks the method that applies a change to the target system. This method contains the forward migration logic that evolves your system state.

The method can accept dependency-injected parameters from the Flamingock context, including database connections, repositories, and custom dependencies.

Example usage:

 @Change(id = "add-user-email-index", order = "2024-11-15-002", author = "team@example.com")
 public class AddUserEmailIndex {

     @Apply
     public void addIndex(MongoDatabase database) {
         database.getCollection("users")
                 .createIndex(Indexes.ascending("email"));
     }

     @Rollback
     public void removeIndex(MongoDatabase database) {
         database.getCollection("users")
                 .dropIndex("email_1");
     }
 }
