QLOG() << "Tagging memoID " << id << endl;
NodeAssignment* assign = _memo[id];
verify(NULL != assign);
if (NULL != assign->pred) {
PredicateAssignment* pa = assign->pred.get();
verify(NULL == pa->expr->getTag());
verify(pa->indexToAssign < pa->first.size());
pa->expr->setTag(new IndexTag(pa->first[pa->indexToAssign]));
}
else if (NULL != assign->orAssignment) {
OrAssignment* oa = assign->orAssignment.get();
for (size_t i = 0; i < oa->subnodes.size(); ++i) {
tagMemo(oa->subnodes[i]);
}
}
else if (NULL != assign->newAnd) {
