	Version     int
	ChangesetID osm.ChangesetID

	// VersionIndex is the index of the version if sorted from lowest to highest.
	// This is necessary since version don't have to start at 1 or be sequential.
	VersionIndex int
	Timestamp    time.Time
	Committed    time.Time

	// for nodes
	Lon, Lat float64

	// for ways
	Way               *osm.Way
	ReverseOfPrevious bool

	// moving the visible bool here decreases the struct size from
	// size 120 (size class 128) to 112 (size class 112).

}

A Child represents a node, way or relation that is a dependent for annotating ways or relations.

FromNode converts a node to a child.

func FromRelation

func FromRelation(r *osm.Relation) *Child

FromRelation converts a way to a child.

func FromWay

func FromWay(w *osm.Way) *Child

FromWay converts a way to a child.

func (*Child) Update
