protected void acceptIOPerformer(IOPerformer performer, DataBuffer source, int initialOffset)
Parameter
performer
is responsible for I/Oing the
parameter. Users implementing a complex parameter from scratch (i.e. not by extending a pre-existing class
such as Structure
or Pointer
) may wish to override this method to make a performer
visit object internal parts.
