[jira] Commented: (XMLBEANS-263) Would like to have methods to get/set fundamental types as Java wrapper objects e.g. java.lang.Long

["Radu Preotiuc-Pietro (JIRA)" <xm...@xml.apache.org>]

    [ https://issues.apache.org/jira/browse/XMLBEANS-263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12652089#action_12652089 ] 

Radu Preotiuc-Pietro commented on XMLBEANS-263:
-----------------------------------------------

I think between using xget() and isNil() there already are ways to get the information. Most people would need to special-case the null case anyway, so the benefit is minimal and we would like to keep the mapping simple: xs:long maps to Java long all the time.

> > Hello Lawrence,
> > 
> > thank you very much for your help. It helped me understand the basic
> > concept
> > - why you are using XmlLong and the other classes.
> > But what I didn't really understand is why you don't use java.lang.Long
> > for
> > convenience, but the primitive type long.
> > 
> > My Problem is the following:
> > I am working with ibatis (ORM-Tool). For this tool I write xml-mapping
> > files, so called sql-maps, where I specify a class with its properties.
> > So when I query my Database, ibatis looks at this mapping file and then
> > searches for the specified class. When it found the class it creates an
> > instance and fills in the propertys with the help of the getter and setter
> > methods.
> > The problem is that the ORM-Tools work with the Wrapper classes because
> > there a null is possible. If for example a database identifier has null as
> > its value, the ORM-Tool knows that it still has to save this Object to the
> > database, if the value is not null, but for example 0, then the ORM-Tool
> > thinks that the Object is already persistent.
> > Because there are so many classes we just need once, we want to have them
> > generated from XmlBeans.
> > Because of this Problem, neither the primitive type nor the Xml... classes
> > work for us.
> > 
> > To solve this problem for us, I have changed the source code a bit, but
> > that
> > isn't a really code solution because with each new release from XmlBeans,
> > we
> > have to adjust the code again.
> > A nice solution for this specific problem we found with JAXB. There you
> > can
> > specify user definded type within annotations. Is there a plan to
> > implement
> > this feature in XmlBeans? Or is there anything that speaks against it? If
> > there is nothing that speaks against it, I would like to implement the
> > JAXB
> > Standard of specifying user defined types in XmlBeans, but for doing that
> > I
> > need help.
> > 
> > I hope I could clearly state my problem and you can help me.
