Method RemoveRangeWith

pkg/segment/set.go:629–646

RemoveRangeWith removes all segments in the given range. An iterator to the newly formed gap is returned, and all existing iterators are invalidated. The function f is applied to each segment immediately before it is removed, in order of ascending keys. Segments that lie partially outside r are spl

(r Range, f func(seg Iterator))

//
// N.B. f must not invalidate iterators into s.
func (s *Set) RemoveRangeWith(r Range, f func(seg Iterator)) GapIterator {
	seg, gap := s.Find(r.Start)
	if seg.Ok() {
		seg = s.Isolate(seg, r)
		if f != nil {
			f(seg)
		}
		gap = s.Remove(seg)
	}
	for seg = gap.NextSegment(); seg.Ok() && seg.Start() < r.End; seg = gap.NextSegment() {
		seg = s.SplitAfter(seg, r.End)
		if f != nil {
			f(seg)
		}
		gap = s.Remove(seg)
	}
	return gap
}

// RemoveFullRangeWith is equivalent to RemoveRangeWith, except that if any key
// in the given range does not correspond to a segment, RemoveFullRangeWith
