 if (nc != null) {
   synchronized (nc.getNCMonitor()) {
     nc.checkNameChange (db, getName(), sName);

     // set the internal name attribute(s), leaving old name in sOldName

     nc.nameHasChanged (db, sOldName, getName());
   }
 }
 else {
   // set the internal name attribute(s)
 }
 

Parameters:

sName - the new name of the object

db - the DataBasket relative to which the operation is to be performed.
