Domain.java and Namespace.java

[Richard Emberson]

I've been trying to generate an XML Schema definition for the
Domain.xml file. So, I've been looking through the Slide code
and I've reach a point of non-understanding.
Domain.java has the following code:
    Namespace namespace = new Namespace();
    namespace.setName(configuration.getAttribute("name"));
    namespace.setLogger(namespaceLogger);
    Configuration namespaceConfigurationDefinition =
        configuration.getConfiguration("configuration");
    namespace.loadParameters(namespaceConfigurationDefinition);
    Configuration namespaceDefinition =
        configuration.getConfiguration("definition");
    namespace.loadDefinition(namespaceDefinition);
    addNamespace(namespace);
    try {
        Configuration namespaceBaseDataDefinition =
            configuration.getConfiguration("data");
        namespace.loadBaseData(namespaceBaseDataDefinition);
    } catch (ConfigurationException e) {
        info("No basedata found for the namespace");
    }
    namespace.loadConfiguration(namespaceConfigurationDefinition);

Note that this creates a Namespace object, namespace, and then calls
the Namespace instance methods loadParameters(...) and
loadConfiguration(..) (calling loadDefinition(...) and loadBaseData(...)
in between).
Now the Namespace code for those two methods are:

void loadConfiguration(Configuration namespaceConfigurationDefinition)
    throws SlideException {
    getLogger().log("Loading namespace " + getName() + "
        configuration",LOG_CHANNEL,Logger.INFO);
    // Load Namespace Config
    config = new NamespaceConfig();
    config.initializeNamespaceConfig(this,
                                     namespaceConfigurationDefinition);
}
void loadParameters(Configuration namespaceConfigurationDefinition)
    throws SlideException {
    getLogger().log("Loading namespace " + getName() + "
        parameters",LOG_CHANNEL,Logger.INFO);
    // Load Namespace Config
    config = new NamespaceConfig();
    config.initializeNamespaceParameters(this,
                                         namespaceConfigurationDefinition);
}
Note that both Namespace methods instantiate the Namespace instance
variable 'config'; Thus the 'config' instance variable created in the
call to the loadParameters() method is overridden by the creation
in the loadConfiguration() method.
So, my question is: Whats up? Why create a NamespaceConfig object
only to drop it and create a second.
Thanks.
