Java Interfaces
1.The interface of 'Java class for action' is ci.CIAction.java, as follows:
package ci;
public interface CIAction {
public void startAction(CrInstrument instrument,String actionCode,CIDataClass dc,String parameters[]);
public void onExit(int type);
}

Code example:

package ci_example;

public class CIActionExample extends javax.swing.JFrame implements ci.CIAction {
    private javax.swing.JButton jButton1;
    private javax.swing.JTextField jTextField1;
    CrInstrument instrument;
    boolean firstTimeRun=true;
    public CIActionExample() {
        initComponents();
    }

    private void initComponents() {

        jButton1 = new javax.swing.JButton();
        jTextField1 = new javax.swing.JTextField();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        getContentPane().setLayout(null);

        jButton1.setFont(new java.awt.Font("Microsoft JhengHei UI", 0, 24));
        jButton1.setText("Exit");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
        });
        getContentPane().add(jButton1);
        jButton1.setBounds(140, 110, 90, 40);

        jTextField1.setFont(new java.awt.Font("Microsoft JhengHei UI", 0, 24));
        jTextField1.setText("Hello World!");
        getContentPane().add(jTextField1);
        jTextField1.setBounds(30, 30, 350, 40);

        pack();
    }

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        System.exit(0);
    }
    public void startAction(CrInstrument instrument,String actionCode,CIDataClass dataClass,String para[]){
        if(firstTimeRun){
          this.instrument=instrument;
          instrument.setVisible(false);
          firstTimeRun=false;
        }
        if(para.length>0 && para[0].equals("1")){
          //do something
        }
    }
public void onExit(int code){
//do something;
}
}

Usage example:
jex_1

2.The interface of 'Java class for checking data' is ci.CIChkDataClass.java, as follows:
package ci;
public interface CIChkDataClass {
//The input data format is in hex mode, ex: 'E5 F6 45 65'.
public boolean chkData(String data);
}

Code example:

pakage ci_example;
public class CheckData implements ci.CIChkClass{
boolean result=true;
public boolean chkData(String data){
if(data.length()>0) result=true;
else result=false;
}
return result;
}

Usage example:
jex_2

3.The interface of 'Java class for sending command' is ci.CIDataGenerator.java, as follows:
package ci;
   public interface CIDataGenerator {
public byte[] getData();
}

Code example:

/*
* temperature: 20~23 => 20 + 0~10
* humidity: 60% ~ 70% =>60 + 0~10
* CO2 : 500 ~ 600 =>500 + 0~100
*/

package ci_example;

import java.text.SimpleDateFormat;
import java.util.Date;
import ci.CIDataGenerator;

//output data ex: 2017/05/05 21:19:42,K234,23.0,68,564
public class CIDemoDeviceData implements CIDataGenerator {
SimpleDateFormat format=new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
public byte[] getData(){
    String date=format.format(new Date()),id="K234",coordinatorId="COOR01",dummyId="DUMMY";
    double te1=20.0,te2=60.0,te3=500.0;
    int value=180;
    String temp1=""+(te1+Math.random()*5.0);
    String temp2=""+(te2+Math.random()*10.0);
    String temp3=""+(te3+Math.random()*100.0);
    int inx=temp1.indexOf(".");
    if(inx>-1) temp1=temp1.substring(0, inx+2);
    else temp1=temp1+".0";
    inx=temp2.indexOf(".");
    if(inx>-1) temp2=temp2.substring(0,inx);
    inx=temp3.indexOf(".");
    if(inx>-1) temp3=temp3.substring(0, inx);
    String data=date+","+id+","+temp1+","+temp2+","+temp3+","+coordinatorId+",,";
    return data.getBytes();
}
}

Usage example:
jex_3

4.The interface of 'Java class for transforming data value' is ci.CITransferClass.java.
package ci;
public interface CITransferClass {
public double getValue(double value);
}

Code example:

package ci_example:

public double getValue(double value){
return value * 1000.0L;
}
}

Usage example:
jex_4

        int screenWidth=Toolkit.getDefaultToolkit().getScreenSize().width;//parent.getWidth();
        int screenHeight=Toolkit.getDefaultToolkit().getScreenSize().height-20;//parent.getHeight();
        String imageFile=para[1];

              h3=Double.parseDouble(para[3])*w3;
              w2=(int)w3;

        if(new File(imageFile).exists()) {
          BufferedImage img = null;
          try {
             img = ImageIO.read(new File(imageFile));
             iconImage=(Image)img;//img.getScaledInstance(img.getWidth(), img.getHeight(), Image.SCALE_SMOOTH);
           } catch (IOException e) {
               e.printStackTrace();
             }
        } else {

            System.out.println("iconImage is null");
        }
        setLocation((screenWidth-w2)/2,(screenHeight-(h2))/2);//h2+20
    }
    private void initComponents() {

        int h=WelcomeFrameImage.this.getContentPane().getHeight();
        int imageH=h;
        int imageW=w;
        g2.drawImage(iconImage, 0, 0, imageW, imageH, rootPane);
    }
}
}
}

Usage example:
jex_5

.GUI (Graphical User Interface)

cr-Instrument uses swing api to design GUI. The framework of GUI is as following:
guigramework

Each window impliments interface ci.CWindow.java, as following:

package ci;

import javax.swing.*;
public interface CWindow {
    JButton button(int i);
    JCheckBox checkbox(int i);
    JComboBox combobox(int i);
    JLabel label(int i);
    JList list(int i);
    void setVisible(boolean v);
    JScrollPane listScrollpane(int i);
    JPanel panel(int i);
    JRadioButton radiobutton(int i);
    JTable table(int i);
    JScrollPane tableScrollpane(int i);
    JTextField textfield(int i);
    JTextArea textarea(int i);
    JScrollPane textareaScrollpane(int i);
}

So, a user's java program can manipulate swing objects, for example:

package ci_example;

import ci.*;
import javax.swing.*;

public class GUI_example implements CIAction{
CrInstrument instrument;
boolean firstTime=true;
public void startAction(CrInstrument instrument,String actionCode,CIDataClass dc, String para[]){
      if(firstTime){
          this.instrument=instrument;
          firstTime=false;
boolean isCombine=true;
String name="ABC Company";
          instrument.window(2).checkbox(1).setSelected(isCombine);
          instrument.window(2).textfield(2).setText(name);
      }
      if(para.length>0 && para[0].equals("1")){
         instrument.window(1).label(1).setText("Hello world!");
      }
}
public void onExit(int v){
    }
}
