[jira] [Comment Edited] (JDO-652) Provision of a typesafe
refactor-friendly query capability for JDOQL
[ https://issues.apache.org/jira/browse/JDO-652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14735201#comment-14735201 ]

------------------------------------------------------------
What remains on this issue :
1. spec : I don't mind contributing some text. The problem is that most of Ch14 is based around javax.jdo.Query. What I suggest would be updates to 14.1 to mention about JDOQLTypedQuery, an update to Ch14.5 to add the newJDOQLTypedQuery() method. Then insert a new section 14.10 before "Examples" to discuss solely the JDOQLTypedQuery interface. Finally update the "Examples" section to add some examples at the end. Other ideas? Alternately put the new section after examples, and have its examples inline with the various method descriptions.
2. tck : this needs tests. I am not the best person to write these since I've written the majority of the API, and the implementation. Volunteer?

> There are various querying capabilities of this type around. JPA2 has its Criteria query API. Third party solutions like QueryDSL also exist, in its case providing a JDOQL implementation (as well as JPQL, and HQL). We should seriously consider introducing something along these lines in the JDO2.4 timeframe.
