Annotation Type Dao

@Target(value=TYPE)
 @Retention(value=RUNTIME)
public @interface Dao

Annotates an interface that defines a set of query methods, usually (but not necessarily) related to a given entity class.

Example:

 @Dao
 public interface ProductDao {
   @Select
   Product findById(UUID productId);

   @Insert
   void save(Product product);

   @Delete
   void delete(Product product);
 }
 

DAO instances are created via DaoFactory methods.

DAO interfaces can define the following methods:

• Delete
• GetEntity
• Insert
• Query
• QueryProvider
• Select
• SetEntity
• Update
