Class StateIteratorLoader

public class StateIteratorLoader

extends Object

A utility class which invokes the XML parser to extract the IXMLResource instances from the XML file.

Depending on which XML library you have, you will want to specify which XMLReader creator to use. Specify the class which implements the IGetXMLReader interface with the -D option of:

      net.groboclown.util.xmlresource.v1.XMLReaderClass=<class name>
 

where class name is the name of the class which will read in the XMLReader. The default class is the Xerces reader. Default supported implementations are:

• xml4j: net.groboclown.util.xmlresource.v1.xml4j.GetXMLReader (requires xml4j.jar and sax2.jar in the classpath)
• xerces: net.groboclown.util.xmlresource.v1.xerces.GetXMLReader (requires a 1.2.1 compatible build of xerces.jar)

Version:

Alpha 0.9.0 - xml4j + sax2
