java.lang.Object com.softsynth.jmsl.util.SimpleXMLLoader
public class SimpleXMLLoader
Read in an XML file that describes an Object, and recreate the object with values found for all matching get/set methods that handle primitive types (String, boolean, int, double), Example, Class com.widgits.City below has matching get/set methods for popuation
package com.widgits; public class City { int population; public City() { } public void setPopulation(int p) { this.population = p; } public int getPopulation() { return population; } public static void main(String args[]) { try { // create a new City and write it out as an XML file City myCity = new City(); myCity.setPopulation(10000); java.io.PrintWriter pout = new java.io.PrintWriter(new java.io.FileOutputStream("city.xml")); (new com.softsynth.jmsl.score.util.SimpleXMLSaver(myCity, "SomeXMLTag")).writeXML(pout); pout.close(); // now read it back in to create a new object with same population as the saved one com.softsynth.jmsl.score.util.SimpleXMLLoader loader = new com.softsynth.jmsl.score.util.SimpleXMLLoader(); City loadedCity = (City) loader.loadXML("city.xml"); System.out.println("population=" + loadedCity.getPopulation()); } catch (java.io.IOException e) { System.out.println("ERROR in main: " + e); } } }The XML file written in main() looks like this:
(openbracket)SomeXMLTag CLASSNAME="com.widgits.City" Population="10000" (closebracket) (openbracket)/SomeXMLTag (closebracket)
