Class XMLNodeFactory

java.lang.Object
  org.jcsp.net.XMLNodeFactory

All Implemented Interfaces:

Serializable, NodeFactory

public class XMLNodeFactory
extends Object
implements NodeFactory

Factory for node instantiation based on an XML-like file.

The factory uses its own XML parser that supports a sub-set of XML. The current implementation will parse a file compatible with jcsp-config.dtd. The parser does not current test conformance to this DTD. It does not currently support XML comments.

An example of using this class can be seen in CNS.
