Re: Constructor Initialization

Thanks Joe. I'll give that a try. ~Lokesh

the toXML call and special characters like &

I looked into the frequently asked questions but did not find anything about special characters such as &. Is the call to toXML supposed to return an XML string with all special characters such as & escaped? Right now this call “String xml = _xstream.toXML(Object someObject);” does not do it for me. Is there a work around?

Re: XStream subclass

Hi Juraj For this kind of thing, I suggest creating your own Marshaller/Unmarshaller classes - these are called in between each object when (de)serializing the graph and can be used to do weird custom stuff that falls outside the scope of Converters. You can plug your custom classes in using XStream.setMarshallingStrategy(). -Joe On 8/8/05, Juraj Burian <jubu-VIXq6x/3rUk@xxxxxxxxxxxxxxxx> wrote: > Hi Joe > My problem is quite complex :-). > I am generating class via ASM (so class file never exists) let say > before its serialization. > During deserialization I need check some attribute (for example > managed) in XML file and if is managed= "true" I need generate new > class via ASM and instantiate it, instead the original class. > > Example: > <org.jubu.TestBean managed="true"> ->>>>> TestBean (class) is going to > be wrapped with generated class. > ... > </org.jubu.TestBean> > > Of course I want to serialize/deserialize not managed objects by > ordinary way > > Thank you. > J.B. > > Joe Walnes wrote: > > >Hi Juraj > > > >I chose not to use protected fields as it makes it hard for me to > >change the internals of XStream (necessary to add features) without > >breaking backwards compatability with people like yourself. > > > >What I prefer to do is understand how you need to customize XStream so > >I can guide you and, if necessary, add the necessary hooks. > > > >Thanks > >-Joe > > > >On 8/8/05, Juraj Burian <jubu-VIXq6x/3rUk@xxxxxxxxxxxxxxxx> wrote: > > > > > >>Hi. > >>After few hours of work with XStream I realized that it is necessary to > >>give into the developer hands a possibility to create a subclass of > >>XStream object.

Re: XStream subclass

I'm not 100% sure of what you're doing, but the Marshaller/Unmarshaller classes are called for every object in the graph - i.e. everytime a converter calls convertAnother().
