Subject [jira] Commented: (DERBY-942) Add JDBC4 Ease of Development Support

Rick Hillegas commented on DERBY-942:

Hi Anurag,

Thanks for the preliminary peek at this patch. Looks good. I like the way you handled the
optional inclusion of the JDBC4-specific classes in the jar file. I recommend adding class
and method comments to the test classes so that reviewers will know what these tests are supposed
to stress. Thanks for the explanation of why you disabled the SecurityManager and for commenting
the property file accordingly. When we do commit this patch, let's leave the JIRA open to
remind us to re-enable the SecurityManager after mustang fixes its bug.

> The Ease of Development extensions provide a way to create tabular DataSets from queries
and tuple signatures. The jdk ships with a factory for creating these DataSets, which is a
class which implements the QueryObjectGenerator interface. A database can write its own custom
QueryObjectGenerator, or just ship with the default, jdk-shipped version. For this task, we
will simply wire the default jdk-shipped factory into the appropriate methods: Connection.createQueryObject()
and DataSource.createQueryObject().
