- ( void )encodeWithCoder:(NSCoder * )coder
{
    Class clazz = [self class ];
    u_int count;

    objc_property_t * properties = class_copyPropertyList(clazz, & count);
    NSMutableArray * propertyArray = [NSMutableArray arrayWithCapacity:count];
     for ( int i = 0 ; i < count ; i ++ )
    {
         const char * propertyName = property_getName(properties[i]);
        [propertyArray addObject:[NSString  stringWithCString:propertyName encoding:NSUTF8StringEncoding]];
    }
    free(properties);


     for (NSString * name in propertyArray)
    {
        id value = [self valueForKey:name];
        [coder encodeObject:value forKey:name];
    }
}

- (id)initWithCoder:(NSCoder * )decoder
{
     if (self = [super init])
    {
         if (decoder == nil)
        {
             return self;
        }

        Class clazz = [self class ];
        u_int count;

        objc_property_t * properties = class_copyPropertyList(clazz, & count);
        NSMutableArray * propertyArray = [NSMutableArray arrayWithCapacity:count];
         for ( int i = 0 ; i < count ; i ++ )
