示例1: rLog
void
Vineyard<I,It,E>::
start_vine(Iter i)
{
rLog(rlVineyard, "Starting new vine");
AssertMsg(i->sign(), "Can only start vines for positive simplices");
Dimension dim = evaluator->dimension(i);
vines_vector[dim]->push_back(Vine());
i->set_vine(&vines_vector[dim]->back());
i->pair->set_vine(i->vine());
}示例2: k
void
Vineyard<I,It,E>::
record_knee(Iter i)
{
rLog(rlVineyard, "Entered record_knee()");
AssertMsg(evaluator != 0, "Cannot record knee with a null evaluator");
AssertMsg(i->vine() != 0, "Cannot add a knee to a null vine");
