JADE的booktrading中GUI套用解析.doc

内容摘要: . &.那末某个例子看不懂，便览java的读书还要加强一点. &. jade的bookTrading中关于于Agent与gui应用界面结合的例子，实则gui在jade中的套用多么简约，主要是要把jade的Agent类当成一个平常类来应用就足以了。那末某个例子看不懂，便览java的读书还要加强一点。现在我来解析一下，主要是对准BoolSellerAgent类材料和BookSellerGui类文书。大家看BookSellerGui.java的主要框架：import java.awt.*;/表明要用哪些类来兑现gui界面，import java.awt.event.*;import javax.swing.*;/*author Giovanni Caire - TILAB*/class BookSellerGui extends JFrame private BookSellerAgent myAgent;/该Agent作为一个分子，所以在添加图书的时机要调用该事物成员的诀要 private JTextField titleField, priceField; BookSellerGui(BookSellerAgent a) super(a.getLocalName(); myAgent = a;/Agent成员初始化 JPanel p = new JPanel(); p.setLayout(new GridLayout(2, 2); p.add(new JLabel(Book title:); titleField = new JTextField(15); p.add(titleField); p.add(new JLabel(Price:); priceField = new JTextField(15); p.add(priceField); getContentPane().add(p, BorderLayout.CENTER); JButton addButton = new JButton(Add); addButton.addActionListener( new ActionListener() public void actionPerformed(ActionEvent ev) try String title = titleField.getText().trim(); String price = priceField.getText().trim(); myAgent.updateCatalogue(title, Integer.parseInt(price);/调用该成员的法子对图书数据进行更新 titleField.setText(); priceField.setText(); catch (Exception e) JOptionPane.showMessageDialog(BookSellerGui.this, Invalid values. +e.getMessage(), Error, JOptionPane.ERROR_MESSAGE); ); p = new JPanel(); p.add(addButton); getContentPane().add(p, BorderLayout.SOUTH); / Make the agent terminate when the user closes / the GUI using the button on the upper right corner addWindowListener(new WindowAdapter() public void windowClosing(WindowEvent e) myAgent.doDelete();/同样是调用某个方法，干什么的自己猜猜 ); setResizable(false); public void show() pack(); Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); int centerX = (int)screenSize.getWidth() / 2; int centerY = (int)screenSize.getHeight() / 2; setLocation(centerX - getWidth() / 2, centerY - getHeight() / 2); super.show(); 然后是卖书者文件的框架：package examples.bookTrading;import jade.core.Agent;import jade.core.behaviours.*;import jade.lang.acl.ACLMessage;import jade.lang.acl.MessageTemplate;import jade.domain.DFService;import jade.domain.FIPAException;import jade.domain.FIPAAgentManagement.DFAgentDescription;import jade.domain.FIPAAgentManagement.ServiceDescription;import java.util.*;public class BookSellerAgent extends Agent / The catalogue of books for sale (maps the title of a book to its price)private Hashtable catalogue;/ The GUI by means of which the user can add books in the catalogueprivate BookSellerGui myGui;/经意看是个gui界面类的成员/ Put agent initializations hereprotected void setup() / Create the catalogue catalogue = new Hashtable(); / Create and show the GUI myGui = new BookSellerGui(this); myGui.show();/这两句发明当该Agent类一运转，就调用该界面对象的show方法显示出来 / Register the book-selling service in the yellow pages DFAgentDescription dfd = new DFAgentDescription(); dfd.setName(getAID(); ServiceDescription sd = new ServiceDescription(); sd.setType(book-selling); sd.setName(JADE-book-trading); dfd.addServices(sd); try DFService.register(this, dfd); catch (FIPAException fe) fe.printStackTrace(); / Add the behaviour serving queries from buyer agents addBehaviour(new OfferRequestsServer(); / Add the behaviour serving purchase orders from buyer agents addBehaviour(new PurchaseOrdersServer();/ Put agent clean-up operations hereprotected void takeDown() / Deregister from the yellow pages try DFService.deregister(this); catch (FIPAException fe) fe.printStackTrace(); / Close the GUI myGui.dispose(); / Printout a dismissal message System.out.println(Seller-agent +getAID().getName()+ terminating.);/* This is invoked by the GUI when the user adds a new book for sale */public void updateCatalogue(final String title, final int price) addBehaviour(new OneShotBehaviour() public void action() catalogue.put(title, new Integer(price); System.out.println(title+ inserted into catalogue. Price = +price); ); /* Inner class OfferRequestsServer. This is the behaviour used by Book-seller agents to serve incoming requests for offer from buyer agents. If the requested book is in the local catalogue the seller agent replies with a PROPOSE message specifying the price. Otherwise a REFUSE message is sent back. */ private class OfferRequestsServer extends CyclicBehaviour public void action() MessageTemplate mt = MessageTemplate.MatchPerformative(ACLMessage.CFP); ACLMessage msg = myAgent.receive(mt); if (msg != null) / CFP Message received. Process it String title = msg.getContent(); ACLMessage reply = msg.createReply(); Integer price = (Integer) catalogue.get(title); if (price != null) / The requested book is available for sale. Reply with the price reply.setPerformative(ACLMessage.PROPOSE); reply.setContent(String.valueOf(Value(); else / The requested book is NOT available for sale. reply.setPerformative(ACLMessage.REFUSE); reply.setContent(not-available); myAgent.send(reply); else block(); / End of inner class OfferRequestsServer /* Inner class PurchaseOrdersServer.

The seller agent removes the purchased book from its catalogue and replies with an INFORM message to notify the buyer that the purchase has been sucesfully completed. */ private class PurchaseOrdersServer extends CyclicBehaviour public void action() MessageTemplate mt = MessageTemplate.MatchPerformative(ACLMessage.ACCEPT_PROPOSAL); ACLMessage msg = myAgent.receive(mt); if (msg != null) / ACCEPT_PROPOSAL Message received. Process it String title = msg.getContent(); ACLMessage reply = msg.createReply(); Integer price = (Integer) catalogue.remove(title); if (price != null) reply.setPerformative(ACLMessage.INFORM); System.out.println(title+ sold to agent +msg.getSender().getName(); else / The requested book has been sold to another buyer in the meanwhile . reply.setPerformative(ACLMessage.FAILURE); reply.setContent(not-available); myAgent.send(reply); else block(); / End of inner class OfferRequestsServer两个类相互调用以使用gui界面的精神意思我方才断句出来了，其实就跟平常写的java程序是一样的。这下知道gui在jade中怎么用了八。 作者提交的简介: .那末某个例子看不懂，便览java的读书还要加强一点.大家看BookSellerGui.java的主要框架： import java.awt.*;/
