Interface RotationAngle

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface RotationAngle

Determines how an icon is to be rotated depending on the primitive to be displayed.

Since:

8199 (creation), 10599 (functional interface)

Method Summary

Modifier and Type	Method and Description
static RotationAngle	buildStaticRotation(double angle) Always returns the fixed angle.
static RotationAngle	buildStaticRotation(java.lang.String string) Parses the rotation angle from the specified string.
static RotationAngle	buildWayDirectionRotation() Computes the angle depending on the referencing way segment, or 0 if none exists.
double	getRotationAngle(OsmPrimitive p) Calculates the rotation angle depending on the primitive to be displayed.
static double	parseCardinalRotation(java.lang.String cardinal) Converts an angle diven in cardinal directions to radians.

Method Detail

getRotationAngle

double getRotationAngle(OsmPrimitive p)

Calculates the rotation angle depending on the primitive to be displayed.

Parameters:

p - primitive

Returns:

rotation angle

buildStaticRotation

static RotationAngle buildStaticRotation(double angle)

Always returns the fixed angle.

Parameters:

angle - angle

Returns:

rotation angle

buildStaticRotation

static RotationAngle buildStaticRotation(java.lang.String string)

Parses the rotation angle from the specified string.

Parameters:

string - angle as string

Returns:

rotation angle

parseCardinalRotation

static double parseCardinalRotation(java.lang.String cardinal)

Converts an angle diven in cardinal directions to radians. The following values are supported: n, north, ne, northeast, e, east, se, southeast, s, south, sw, southwest, w, west, nw, northwest.

Parameters:

cardinal - the angle in cardinal directions

Returns:

the angle in radians

buildWayDirectionRotation

static RotationAngle buildWayDirectionRotation()

Computes the angle depending on the referencing way segment, or 0 if none exists.

Returns:

rotation angle
