I don't know if I understand the question.
Why don't you use a member variable in your subclass
of PdfPageEventHelper. Create an instance of your
custom page event class and make sure you have a
setter that allows you to change the value of the
variable. Check this value in the onEndPage method
to make whatever decision is needed (add a watermark,
don't add a watermark, add something else,...).
