   1.559 +@SYMTestActions         CStreamStore provides couple of virtual methods in its private section:
   1.560 +                        DoExtendL(), DoDeleteL(), DoReplaceL(), DoReclaimL().
   1.561 +                        They are no-ops and are expected to be overriden in the class derived from
   1.562 +                        CStreamStore. Their implementations leave with KErrNotsupported. 
   1.563 +                        The test uses a class derived from CStreamStore, which class does not implement
   1.564 +                        virtuals mentioned above. These virtuals should leave with KErrNotSupported when called.
