在BlackBerry中使用持久存储

我正在开发一个黑莓应用程序。我想在手机中存储多个用户的详细信息。我必须为每个用户存储用户名、名字、姓氏、电子邮件id、电话号码等数据。任何人都可以为我提供一个持久存储的示例代码，我可以使用它将所有这些数据存储在一个向量中并在以后检索。

下面是我的一个项目中的一些代码

public class PreferencesStore 
{
    // Not a real key, replace it with your own.    
    private static long m_lTabulaRectaKey = 0l;

    public static Vector getTabulaRectas()
    {
        Vector vecTabulaRectas = new Vector();

        PersistentObject poObject = PersistentStore.getPersistentObject(m_lTabulaRectaKey);

        if(poObject.getContents() != null)
        {
            vecTabulaRectas = (Vector)poObject.getContents();
        }

        return vecTabulaRectas;

    }

    public static void addTabulaRecta(TabulaRecta a_oTabulaRecta)
    {
        Vector vecTabulaRectas = getTabulaRectas();

        vecTabulaRectas.addElement(a_oTabulaRecta);

        PersistentObject poObject = PersistentStore.getPersistentObject(m_lTabulaRectaKey);

        poObject.setContents(vecTabulaRectas);

        poObject.commit();
    }
}
