Support specification of exact class in SingleFieldIdentity -----------------------------------------------------------
Key: JDO-630 URL: https://issues.apache.org/jira/browse/JDO-630 Project: JDO Issue Type: Improvement Components: api2 Reporter: Andy Jefferson Fix For: JDO 2 maintenance release 3 When calling PersistenceManager.getObjectById() with a SingleFieldIdentity, there seems to be no way of avoiding the following (if the implementation decides to do so): "It is an implementation decision whether to access the data store, if required to determine the exact class. This will be the case of inheritance, where multiple <code>PersistenceCapable</code> classes share the same ObjectId class." Now when I know for sure that the targetClassName of the given SingleFieldIdentity already denotes the correct class for the given id, how can I avoid that additional roundtrip to the database for finding the exact class? It would be useful to have a way of specifying a SingleFieldIdentity to be for the exact class specified. This could be done by addition of methods void setExact(boolean flag); boolean getExact(); to SingleFieldIdentity -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
