Package com.codename1.annotations.db

package com.codename1.annotations.db

Mapping annotations for managed database persistence. Relationships, lifecycle callbacks, converters, and identifier generation are processed at build time. They require the Codename One annotation processor and entity enhancement; they are not runtime reflection annotations or JPA.

The established Entity, Id, Column, and DbTransient annotations remain in com.codename1.annotations for source compatibility. Import those together with this package when declaring managed entity mappings.
