java.lang.Object

org.jcsp.net.settings.ConfigReader

All Implemented Interfaces:

XMLConfigConstants

public class ConfigReader
extends Object
implements XMLConfigConstants

Used internally by the JCSP network infrastructure to load a configuration from an XML file.

This is not a full XML reader, and is capable of reading only a subset of XML.

Constructor Details

ConfigReader

public ConfigReader(InputStream instream)
             throws IOException

Constructs a new configuration from the given source stream. This will attempt to parse the file using recursive-descent approach.

Parameters:

instream - source of the XML configuration.

Throws:

IOException - if there is a problem with the stream or the file is improperly formatted.

ConfigReader.XMLValidationException - if there is a symantic problem with the configuration.

Method Details

main

public static void main(String[] args)

Diagnostic routine. This can load an XML configuration file and then display the configuration structure constructed. Specify the name of the file as the first command line parameter.
