You define your object like any other class in Java. The only requirement is that all persistent objects (objects you would like to store in the database) will have to inherit from ooObj. Here's an example:
Car.java
import com.objy.db.app.*;
class Car extends ooObj
{
public int VIN;
public void setVin(int vinNum)
{
markModified(); //to mark object for update
VIN = vinNum;
}
public int returnVin()
{
fetch(); //mark object for read
return VIN;
}
};
Be sure to include the path in your application to include these class files.
createObj.java
import com.objy.db.*;
import com.objy.db.app.*;
public class createObj
{
public static void main(String[] args)
{
String bootfile = "test.boot"; //insert bootfile name here
String dbName = "testDB"; //insert db name here
String contName = "testCont"; //insert cont name here
Connection connection = null;
Session session = null;
try
{
connection = Connection.open(bootfile, oo.openReadWrite);
connection.loadSchemaClasses(true);
session = new Session();
ooFDObj fd = session.getFD();
session.begin();
ooDBObj db = null;
if(fd.hasDB(dbName))
{
db = fd.lookupDB(dbName);
}
else
{
db = fd.newDB(dbName);
}
ooContObj cont = null;
if(db.hasContainer(contName))
{
cont = db.lookupContainer(contName);
}
else
{
cont = new ooContObj();
db.addContainer(cont, 0, contName, 0, 0);
}
Car obj = new Car();
cont.cluster(obj);
session.commit();
}
catch(Exception e)
{
e.printStackTrace();
session.abort();
}
}
}
