  public static final void requestRewriteOfEvolvedBlobbedObject()
  
  Invoking this method will tell the PDS that the blobbed or smallblobbed object being deserialized in the current method context needs to be written back into the database in its current class schema prior to being returned to the caller. This rewrite will only occur if the db.properties property wt.pom.blobRewrite.enabled is set to true.
  This method should be called from the read old version methods of serializable classes, but only after successful deserialization and only if the object was deserialized from a PDSObjectInput.
