Project overview
This feature is about adding the new attribute level mappings annotations supported by the EclipseLink JPA extension.
Goals:
- Add JPA Details view widgets for the BasicCollection, BasicMap and Transformation annotations
- Add JPA Details view widgets for eclipselink-orm.xml basic-collection, basic-map and transformation elements
- Provide the appropriate defaults and validation for these mappings
Concepts
Present any concepts relevant to the feature.
EclipseLink BasicCollection annotation documentation
EclipseLink BasicMap annotation documentation
EclipseLink CollectionTable annotation documentation
EclipseLink Transformation annotation documentation
Requirements / Functionality
Basic Collection
- Supported in Entity, MappedSuperclass, and Embeddable classes.
- Default fetch type is Lazy
- Default Value Column name is <field/property-name>
- Default @CollectionTable name is <Entity-name>_<field/property-name>
- Validation
- Attribute type must be Collection, Set, or List
Basic Map
- Supported in Entity, MappedSuperclass, and Embeddable classes.
- Default fetch type is Lazy
- Default Value Column name is <field/property-name>
- Default Key Column name is <field/property-name>_KEY
- Default @CollectionTable name is <Entity-name>_<field/property-name>
From the EclipseLink docs, we can create validation for this. Need to verify that I understand the second statement: Note: If you specify @BasicMap on an attribute of type Collection, EclipseLink will throw an exception: the type must be Map. If you specify the fetch type as LAZY, Map implementation classes are also not valid.
Transformation
- Supported in Entity, MappedSuperclass, and Embeddable classes.
