I want to create constructor which takes xml as string and all variables would be fill from that. That xml is created by XStream so I think that something like this would work but don´t know what to add to left side:
public xmlpacket(String xml)
{
XStream xstream = new XStream(new DomDriver());
.... = (xmlpacket)xstream.fromXML(xml);
}
Thank you
You can make use of a static method.
public static XMLPacket unmarshall(String xml) {
XStream xstream = new XStream(new DomDriver());
return (XMLPacket)xstream.fromXML(xml);
}
Notice how I renamed your class. Now it adheres to Java Naming Conventions.
If you've created the classes you need and the xstream aliases for the classes then
XMLPacket packet = (XMLPacket)xstream.fromXML(xml);
But you should probably create a method for this and not do it in the constructor.
XStream will create the instance of the object for you. So unless you want to copy all the attributes of the XStream-created packet to the packet you're constructing, it makes no sense to do that in a constructor. Create a factory method instead:
public static XmlPacket fromXml(String xml) {
XStream xstream = new XStream(new DomDriver());
return (XmlPacket) xstream.fromXML(xml);
}
