Example 1
ModuleFactory(String referenceModuleID, Class<? extends IModule> clazz) throws ModuleInitException {
	// NOTE: Instanciable only from ModuleRegistry
	this.clazz = clazz;
	this.referenceModuleID = referenceModuleID;
	
	// Determine configurable fields via reflection
	for(Field field : clazz.getFields()) {
		ModuleParameter cfg = field.getDeclaredAnnotation(ModuleParameter.class);
		if( cfg == null )
			continue;
		try {
			field.setAccessible(true);
		}
		catch(SecurityException e) {
			throw new ModuleInitException("Failed to acquire reflection access to field '" + field.toString() + "', annotated by @ModuleParameter.", e);
		}
		configurableFields.put(cfg.value(), field);
	}

	// Determine overrides
	overridableMethods.putAll(ModuleOverrideHandler.getOverrideMethodsFromClass(clazz, true));
