Enum Snap.Position

java.lang.Object

java.lang.Enum<Snap.Position>

com.graphhopper.storage.index.Snap.Position

All Implemented Interfaces:

Serializable, Comparable<Snap.Position>

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.

Method Detail

values

public static Snap.Position[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Snap.Position c : Snap.Position.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Snap.Position valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
