Interface IObexObjectPassing

public interface IObexObjectPassing

This interface has to be implemented to send objects over the provided ObexObjectPassing (OOP) library. With this library you can send objects via bluetooth connection with little effort. It maybe also useful for storing objects in RMS.
An example of a class implementing IObexObjectPassing looks like the following:

 
 package org.coffeecrew.da.entity;
 
 import java.io.ByteArrayInputStream;
 import java.io.ByteArrayOutputStream;
 import java.io.DataInputStream;
 import java.io.DataOutputStream;
 import java.io.IOException;
 import org.coffeecrew.mobile.oop.IObexObjectPassing;
 
 public class Person implements IObexObjectPassing
 {
    // entity fields
    private String name = null;
    private String vorname = null;
    private int age = 0;
    
    // Globals
    private ByteArrayOutputStream bout = null;
    private DataOutputStream dout = null;
    
    private ByteArrayInputStream bin = null;
    private DataInputStream din = null;
    
    // Creates a new instance of Person
    public Person()
    {
    }
    
    public Person(String name, String vorname, int age)
    {
        this.name = name;
        this.vorname = vorname;
        this.age = age;
    }
    
    // Return the datastructure as byte[]
    public byte[] getAsByteArray()
    {
        bout = new ByteArrayOutputStream();
        dout = new DataOutputStream( bout );
        byte[] ret = null;
        
        try
        {
            
            // Write values
            dout.writeUTF(name);
            dout.writeUTF(vorname);
            dout.writeInt(age);
            dout.flush();
            
            //do temp copy so we can close the writers
             
            ret = bout.toByteArray();
            dout.close();
            bout.close();
        }
        catch (IOException ex)
        {
            ex.printStackTrace();
        }
        
        
        return ret;
    }
     
    public void setObjectData(byte[] ba)
    {
        bin = new ByteArrayInputStream(ba);
        din = new DataInputStream(bin);
        try
        {
            
            this.name = din.readUTF();
            this.vorname = din.readUTF();
            this.age = din.readInt();
            
            din.close();
            bin.close();
        }
        catch (IOException ex)
        {
            ex.printStackTrace();
        }
        
    }
    
    // ACCESSOR / MUTATOR methods
    public String getName()
    {
        return name;
    }
    
    public void setName(String name)
    {
        this.name = name;
    }
    
    public String getVorname()
    {
        return vorname;
    }
    
    public void setVorname(String vorname)
    {
        this.vorname = vorname;
    }
    
    public int getAge()
    {
        return age;
    }
    
    public void setAge(int age)
    {
        this.age = age;
    }
 
 }
