All Implemented Interfaces:
Serializable, Comparable<Snap.Position>, Constable
Enclosing class:
Snap
public static enum Snap.Position extends Enum<Snap.Position>
Whether the query point is projected onto a tower node, pillar node or somewhere within the closest edge.

Due to precision differences it is hard to define when something is exactly 90° or "on-node" like TOWER or PILLAR or if it is more "on-edge" (EDGE). The default mechanism is to prefer "on-edge" even if it could be 90°. To prefer "on-node" you could use e.g. GHPoint.equals with a default precision of 1e-6.
