The canConvert method is plain simple. Let’s go for converting a Calendar in a localized string Now we can output the data So we make use of an ‘alias’ to change this full class name to something more ‘human’, for example ‘person’. Let’s enhance the Person with a String representation, that contains all necessary text to recreate the instance:. 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.

So we make use of an ‘alias’ to change this full class name to something more ‘human’, for zml ‘person’. Try using an attribute called fullname in the person tag instead of creating a new child node.
While XStream is capable of converting this class without any problem, we write our own custom converter just for demonstration. 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. Take a look at this question: I removed the junk characters on my xtsream making sure the string “startsWith” the correct xml header. But we reuse the converters registered in XStream for our member fields and handle null values:.
And the other way around Now we tell domdruver calls us that we can handle only Person’s and nothing else, including those classes which extends Person. Email Required, but never shown.

I believe they are using the XmlSerializer class provided by.

Now we can output the data It may be worth posting the XML you have to thoughtwworks. It is just a root node and about 25 child nodes of varying data types byte array, string, int, boolean. Let’s enhance the Person with a String representation, that contains all necessary text to recreate the instance:. I would expect XStream to assume that it’s performed the serialisation as well. And now let’s go to the unmarshal.
The unmarshal method ensures the valid value for the gender by throwing a ConversionException for invalid entries.
XStream – Converter Tutorial
We use the moveDown and moveUp methods to move in the tree hierarchy, so we can simply moveDownread the value and moveUp. I believe this has to do with XStream not knowing what classes to match up with certain XML elements based on their name.
I get the XML cannot change format of XML from a server and try to save its node information to the domdrive variables in a certain class. This is not allowed. I will look more into this option. This time we want to reuse our already written converters for the Person and the Calendar and add an own attribute for the gender. John Saunders k 22
