I have a generic Lock entity which Locks a record in the database.

It contains a generic method called
LockRecord(objectType,objectInstance)

I have different objects implementing the lock, which do you is better?

1.

Object1 class

LockObject1(object1instance)
{
//do necessary stuffs for object1instance
Lock.LockRecord(objectType.Object1,object1instance )
}

Object2 class

LockObject2(object2instance)
{
//do necessary stuffs for object2instance
Lock.LockRecord(objectType.Object2,object2instance )
}

or

2. at the LockRecord method i will have the following:

LockRecord(objectType,objectInstance)
{
switch(objectType)
{
case objectType.object1 : do object1 stuff;break;
case objectType.object2 : do object2 stuff;break;
.
.
.
}
}

I think option 1 is better because of loose coupling. Do you guys heve a better way of implementing this?
