◆ apply_modification()

virtual |
see SOCOracle::apply_modification() for the general use, here oracle_modification has a special role if it can be cast to an AMFModification
if oracle_modification cannot be cast to an SOCSupportModification it is assumed that all append modifications amount to have already been carried out on *this seperately before this routine is called. In particular, it is only checked whether the new dimension matches the one given by oracle_modification, the old dimension is ignored. If this does not hold, the routine stops with an error. Otherwise it checks the other stuff as if a suitable SOCSupportModification has just been executed.
Reimplemented from ConicBundle::SOCOracle.
