Graylin Kim updated DBUTILS-113:
--------------------------------
Attachment: bean_enums3.diff
bq. 1. Line 94 and 95 can be collapsed
Sure, I was just trying to conform to the nested conditional structure above
it. I've attached a diff with this change.
bq. 2. You do not need reflection because DbUtils 1.6 is set to Java 1.6, you
simply could cast params\[0\] to Enum and call the static valueOf method. Catch
blocks for NoSuchMethodException and SecurityException would be obsolete.
This was my original intention but I could not figure out how to do it.
Class<?> can't be cast to an enum so I have to create a new instance of the
Class<Enum>:
{{((Class<Enum>)params\[0\]).newInstance()}}
The Enum class forces us to use the {{valueOf(Class<T>, String)}} signature. I
can't figure out how you would turn Class<?> into a valid Class<T> for the
valueOf method.
I wouldn't call myself a Java expert, perhaps you know of a different way?

> When using commons-dbutils I frequently use enum values with corresponding
> enum in the database. In this situation, using the BeanListHandler produces
