public class XStreamer
extends Object

Self-contained XStream generator. The class is a utility to write XML streams that contain additionally the XStream that was used to serialize the object graph. Such a stream can be unmarshalled using this embedded XStream instance, that kept any settings.

Method Detail

toXML

public String toXML(XStream xstream,
           Object obj)
             throws ObjectStreamException

Serialize an object including the XStream to a pretty-printed XML String.

Throws:

ObjectStreamException - if the XML contains non-serializable elements

XStreamException - if the object cannot be serialized

Since:

1.2

toXML

public void toXML(XStream xstream,
         Object obj,
         Writer out)
           throws IOException

Serialize an object including the XStream to the given Writer as pretty-printed XML.

Warning: XStream will serialize itself into this XML stream. To read such an XML code, you should use fromXML(Reader) or one of the other overloaded methods. Since a lot of internals are written into the stream, you cannot expect to use such an XML to work with another XStream version or with XStream running on different JDKs and/or versions. We have currently no JDK 1.3 support, nor will the PureReflectionConverter work with a JDK less than 1.5.

Throws:

IOException - if an error occurs reading from the Writer.

XStreamException - if the object cannot be serialized

Since:

1.2

fromXML

public Object fromXML(String xml)
               throws ClassNotFoundException,
                      ObjectStreamException

Deserialize a self-contained XStream with object from a String. The method will use internally an XppDriver to load the contained XStream instance.

Throws:

ClassNotFoundException - if a class in the XML stream cannot be found

ObjectStreamException - if the XML contains non-deserializable elements

XStreamException - if the object cannot be deserialized

Since:

1.2

             String xml)
               throws ClassNotFoundException,
                      ObjectStreamException

Deserialize a self-contained XStream with object from a String.

Throws:

ClassNotFoundException - if a class in the XML stream cannot be found

ObjectStreamException - if the XML contains non-deserializable elements

XStreamException - if the object cannot be deserialized

Since:

fromXML

public Object fromXML(Reader xml)
               throws IOException,
                      ClassNotFoundException

Deserialize a self-contained XStream with object from an XML Reader. The method will use internally an XppDriver to load the contained XStream instance.

Throws:

IOException - if an error occurs reading from the Reader.

ClassNotFoundException - if a class in the XML stream cannot be found

XStreamException - if the object cannot be deserialized
