Subject [jira] Commented: (JDO-515) Allow custom settings for some annotation enum values
Date Mon, 13 Aug 2007 17:07:35 GMT

    [ https://issues.apache.org/jira/browse/JDO-515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12519473

Craig Russell commented on JDO-515:

I suppose we should change all of the defaults from UNKNOWN to UNSPECIFIED in all the annotations.
[Bruiser:javax/jdo/annotations] clr% grep UNKNOWN *
DatastoreIdentity.java:    IdGeneratorStrategy strategy() default IdGeneratorStrategy.UNKNOWN;
Discriminator.java:        default DiscriminatorStrategy.UNKNOWN;
DiscriminatorStrategy.java:    UNKNOWN,
Element.java:    ForeignKeyAction deleteAction() default ForeignKeyAction.UNKNOWN;
Element.java:    ForeignKeyAction updateAction() default ForeignKeyAction.UNKNOWN;
ForeignKeyAction.java:    UNKNOWN,
IdGeneratorStrategy.java:    UNKNOWN,
IdentityType.java:    UNKNOWN,
Join.java:    ForeignKeyAction deleteAction() default ForeignKeyAction.UNKNOWN;
Key.java:    ForeignKeyAction deleteAction() default ForeignKeyAction.UNKNOWN;
Key.java:    ForeignKeyAction updateAction() default ForeignKeyAction.UNKNOWN;
PersistenceCapable.java:    IdentityType identityType() default IdentityType.UNKNOWN;
PersistenceModifier.java:    UNKNOWN,

>            Reporter: Andy Jefferson
>             Fix For: JDO 2 maintenance release 1
> JDO2.1 annotations utilise some enums defining the acceptable values for various strategies.
The following need changing to allow implementations to provide custom values.
> @Persistence "valueStrategy", @DatastoreIdentity "strategy" are of the type IdGenerationStrategy.
 Changes required :
> 1. IdGenerationStrategy needs UNKNOWN changing to UNSPECIFIED.
> 2. @Persistence : add "customValueStrategy"
> 3. @DatastoreIdentity : add "customStrategy"
> @Inheritance "strategy" is of type InheritanceStrategy. Changes required :
> 1. InheritanceStrategy needs UNSPECIFIED adding.
> 2. @Inheritance : change "strategy" to have default of UNSPECIFIED
> 3. @Inheritance : add "customStrategy"
