refreshOpaqueToken of LockMethod

[Jojada J Tirtowidjojo]

Hi all,

The LockMethod class of webdav client library has 'refreshOpaqueToken' as
well as 'lockToken' fields.

Below is the code of its generateHeaders(String host, State state) method:

public void generateHeaders(String host, State state)   {
  ...
  if (isRefresh())      {
     setHeader("If", "(<" + refreshOpaqueToken + ">)");
  }
 ...
}

The questions are:
1. What are the functional difference between lockToken and
refreshOpaqueToken ? Currently, lockToken contains an opaquelocktoken.
2. When is refreshOpaqueToken really set ?
3. If refreshOpaqueToken had not been implemented yet, could I suggest
using lockToken in the above code ?

Thanks.
Jojada.-
