Classes

Dao

Annotation for create data access object. It must be applied on an abstract class. In the class that this annotation applied on, you can define methods for access and manipulate data in tables

Delete

Annotation for define a delete method. Methods that annotated with this annotation can have only one input parameter that is an Entity and cannot be nullable. The return type can be Future

DeleteParam

Insert

Annotation for define an insert method. Methods that annotated with this annotation can have only one input parameter that is an Entity or List of an Entity and cannot be nullable. If the input parameter is Entity, the return type can be Future

InsertParam

Query

Annotation for define raw query for access or manipulate data. You have to pass your raw query as a String to query property of this annotation. You have to detect the return type, yourself. You can fetch raw results as List<Map<String, Object?>>? by using RawData class as the return type. Also, you can fetch results as a custom class. In this case you must pass that custom class to the SingularReturnType annotation. For better query, you can have any number of input parameters and you can pass these parameters to query using the colon(:) symbol. Examples:

QueryParam

SingularReturnType

Transactional

Update

Annotation for define an update method. Methods that annotated with this annotation can have only one input parameter that is an Entity or List of an Entity and cannot be nullable. If the input parameter is Entity, the return type can be Future
