weatherextensionhandler.java

目前在JAVA下编程时对XML的操作很重要

package com.extension;
import com.weather.*;
import org.apache.xmlbeans.*;


public class weatherExtensionHandler {


        /**
         * Converts "Temperature" element's value in Celsius, then returns it.
         */
        public static float getTemperatureInCelsius(XmlObject xo) {

			LocalWeatherDocumentXmlBean.LocalWeather localWeatherElement = (com.weather.LocalWeatherDocumentXmlBean.LocalWeather)xo;

			return ((localWeatherElement.getTemperature() - 32) * 5/9);

		}

        /**
         * Converts "Visibility" element's value in Metric units i.e. Kilometers, then returns it.
         */
        public static float getVisibilityInKilometers(XmlObject xo) {

			LocalWeatherDocumentXmlBean.LocalWeather localWeatherElement = (com.weather.LocalWeatherDocumentXmlBean.LocalWeather)xo;
			return (localWeatherElement.getVisibility() * 1.609f);


		}

}
