JPA Annotations for Fields

The way a field of a persistable class is managed by JPA can be set by the following annotations:

• javax.persistence.Basic - JPA Annotation
• javax.persistence.Embedded - JPA Annotation
• javax.persistence.ElementCollection - JPA Annotation
• javax.persistence.Id - JPA Annotation
• javax.persistence.EmbeddedId - JPA Annotation
• javax.persistence.Version - JPA Annotation
• javax.persistence.Transient - JPA Annotation

Additional annotations (and enum) are designated for enum fields:

• javax.persistence.Enumerated - JPA Annotation
• javax.persistence.MapKeyEnumerated - JPA Annotation
• javax.persistence.EnumType - JPA Enum

Other additional annotations (and enum) are designated for date and calendar fields:

• javax.persistence.Temporal - JPA Annotation
• javax.persistence.TemporalType - JPA Enum
• javax.persistence.MapKeyTemporal - JPA Annotation

Chapter 2 of the ObjectDB manual explains how to use all the above annotations.
