So we make use of an ‘alias’ to change this full class name to something more ‘human’, for example ‘person’. We convert no derived classes this time, since they might have additional fields. It is just a root node and about 25 child nodes of varying data types byte array, string, int, boolean.

If the implementation of Birthday ensures, that none of its thpughtworks could hold a null value and gender contains a valid value, then we could drop the null condition in the marshal method and in unmarshal we could omit the loop as well as the comparison of the tag names:.

I think you may have a lot of work ahead of you depending on the XML you have to deserialise.

I believe this has to do with XStream not knowing what classes to match up with certain XML elements based on their name. While XStream is capable of converting this class without any problem, we write our own custom converter just for demonstration.
This time we want to reuse our already written converters for the Person and the Calendar and add an own attribute for the gender. The canConvert method is plain simple. I will look more into this option. Can anyone shed some light on these exceptions?
If this is not what you want, change your canConvert method to return true only if class equals GregorianCalendar. Note, that in implementation of a SingleValueConverter is required for attributes, since these objects have to be represented by a single string only.
Note, that attributes will always have to be coj and read first. Now let’s convert anything which extends Calendar: Ok so you simply need to make sure that content gets removed before you attempt to deserialize it.
I would expect XStream to assume that it’s performed the serialisation as well. My function is at the bottom and I tried to register a new converter for the XStream object thinking that it was because one variable is a byte array but still no luck.
Content is not allowed in prolog. But we reuse the converters registered in XStream for our member fields and handle null values:. Sign up using Facebook. Assaf Israel 2 9. Let’s go for converting a Calendar in a localized string The XStream package can serialize my class fine. Take a look at this question: Sign up using Email and Password.
Since the String representation is complete, a nested element is not necessary anymore:. Try tthoughtworks an attribute called fullname in the person tag instead of creating a new child node. I removed the junk characters on my end making sure the string “startsWith” the correct xml header. You work on a stream and accessing the value of a tag or its members will close the surrounding tag that is still active when the method is called.
