const_iterator - Create an iterator that isn't pointing anywhere.

◆ advanceTo()

template<typename KeyT, typename ValT, unsigned N = IntervalMapImpl::NodeSizer<KeyT, ValT>::LeafSize, typename Traits = IntervalMapInfo<KeyT>>
void llvm::IntervalMap< KeyT, ValT, N, Traits >::const_iterator::advanceTo ( KeyT  x)
inline

advanceTo - Move to the first interval with stop >= x, or end().

The search is started from the current position, and no earlier positions can be found. This is much faster than find() for small moves.
