USF Examples

Basics

Basic usage in classes

Example Class to Export:

import eu.kimb_technologies.usf.Atom;
import eu.kimb_technologies.usf.USFInteger;
import eu.kimb_technologies.usf.USFList;
import eu.kimb_technologies.usf.USFSaveable;

public class Position implements USFSaveable {

	private int xPos;
	
	private int yPos;

	public Position() {
		this.xPos = -1;
		this.yPos = -1;
	}
	
	public Position(int xPos, int yPos) {
		this.xPos = xPos;
		this.yPos = yPos;
	}
	
	public int getY() {
		return yPos;
	}
	
	public int getX() {
		return xPos;
	}

	@Override
	public Atom toAtom() {
		USFList list = new USFList();
		list.add( new USFInteger( this.xPos ) );
		list.add( new USFInteger( this.yPos ) );
		return list;
	}

	@Override
	public void fromAtom(Atom atom) t {
		try {
			USFList list = ((USFList) atom);	
			this.xPos = ((USFInteger) list.get(0)).getValue();
			this.yPos = ((USFInteger) list.get(1)).getValue();
		} catch( Exception e ) {
			System.out.println("Error on loading a position!");
		}
	}
	
}

Now you can export and import this way:

Position pos = new Position(12,33);

System.out.println( USFParser.toUSF( pos ) );
	// [12,33]
USFParser.saveToFile("/home/user/example.usf", pos);
	// will create file /home/user/example.usf with content [12,33]  

	// creating "default" object
Position posImport = new Position();
	// importing saved data
posImport.fromAtom( USFParser.loadFromFile("/home/user/example.usf") );

	// or just:
posImport.fromAtom( USFParser.parse("[12,33]") );

MVC Ex- & Import

Exporting and Importing a Model from MVC-Pattern.

• Each model class has to implement the USFSaveavle-Interface
• E.g. the model class to export
