Re: [jibx-users] Unmarshall on an existing object

[Tudor Olteanu]

I found another thread which describes the issue in more detail (http://www.mail-archive.com/jibx-users@lists.sourceforge.net/msg01249.html) Anyway, I managed to get a list with the fields that were received but I have the names of the tags. What I will need for each tag name, is the name of its corresponding property from the mapping class. Please let me know how can I do this. Thanks, Tudor Thomas Jones-Low wrote: Use a default. The Jibx <value> tag takes an default= attribute. This is only allowed on optional values (like you have) and if the optional value is missing, the corresponding set-method is called with the default. If you have the default attribute set to "missing" or some other out of bounds value, the Set-method now knows when to leave the value alone, and when to update it. Tudor Olteanu wrote: Since "null" is also a possible value for some fields, I can't assume that null values are corresponding to missing fields. So what I need is a way to know if an optional field was/wasn't present in xml. Thomas Jones-Low wrote: Using a existing object will require the use of the Factory attribute for the binding. This is a static method which returns the instance to be worked on. The original values to be kept will need a set-method rather than the default setter, to check for the null value and not update them. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
