org.nthx.pat

When I want to solve "baptism problem", then I cannot simply put whole object into GenericCommand GenericCommand .

The trick is not to store objects involved in transaction:

• target object - on which method is invoked
• argument objects

This interface is introduced into root object (@@ pat.root), so it is possible to execute code like this:

 {
 ((Persisteble)myRoot).takeSnapshot();
 }
 

This is part of public API.
