[jira] Commented: (JDO-677) Ability to mark a class as read-only
[ https://issues.apache.org/jira/browse/JDO-677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13008507#comment-13008507 ] Craig L Russell commented on JDO-677: - Nothing in the specification calls for writing to the database at the time the field is changed, so the checking probably should be done at flush/commit, even for datastore transactions. This is different from a class that knows that it is read-only, or might be configured to be read-only at the modeling level. In this case, mutators should throw an exception. For an example of this kind of behavior, see java.util.Collections unmodifiableCollection method that returns a read-only instance. > Ability to mark a class as read-only > > > Key: JDO-677 > URL: https://issues.apache.org/jira/browse/JDO-677 > Project: JDO > Issue Type: New Feature > Components: api, specification, tck >Reporter: Andy Jefferson > > While JDO already allows a datastore to be marked as read-only > (javax.jdo.option.ReadOnly), it would be desirable to extend this down to > class-level.

Minutes: JDO TCK Conference Call Friday, Mar 18, 9 am Pacific Time
Attendees: Michelle Caisse, Craig Russell Agenda: 1. TCK State Transitions test: the way the test creates e.g. persistent dirty instances is to get a random persistent instance from the database, make it hollow, and then write the field. The specification states "A hollow instance transitions to persistent- dirty if a change is made to any managed field. " Does this apply if the value written is the same as the current value? It's deliberately vague. The test could be improved by implementing the getPersistentDirtyInstance to write the value of the static field into the persistent field instead of the value 23. There are 50 instances created at the beginning of the test because at the time the test is run, you don't know how many instances are needed. It depends on the features supported by the iut. Patches welcome. 2.
