Enum Annotation.AnnotationType

java.lang.Object

java.lang.Enum<Annotation.AnnotationType>

com.telenav.mapkit.Annotation.AnnotationType

All Implemented Interfaces:

Serializable, Comparable<Annotation.AnnotationType>

Enclosing class:

Annotation

public static enum Annotation.AnnotationType
extends Enum<Annotation.AnnotationType>

The map engine supports several annotation types. They are defined by the AnnotationType Enum as follows

Enum Constant Summary

Enum Constants

Enum Constant and Description
Flat A flat annotation is an annotation placed flatly on the surface of the map, regardless of the camera position and orientation.
LatLonToScreen2D An alternative way to position a 2D screen annotation is to convert a latitude-longitude coordinate to a screen coordinate, and use that screen coordinate to position a screen annotation.
Screen2D Annotations can also be placed and rendered in screen coordinates (or, rather, viewport coordinates).
ViewerFacing A viewer-facing annotation always faces the camera regardless of the camera position or tilt.

Enum Constant Detail

Flat

public static final Annotation.AnnotationType Flat

A flat annotation is an annotation placed flatly on the surface of the map, regardless of the camera position and orientation. The annotation is aligned with north (and, therefore, appears upright when north is up).

ViewerFacing

public static final Annotation.AnnotationType ViewerFacing

A viewer-facing annotation always faces the camera regardless of the camera position or tilt. It lives in the 3D world, so annotations that are farther away appear smaller.

Screen2D

public static final Annotation.AnnotationType Screen2D

Annotations can also be placed and rendered in screen coordinates (or, rather, viewport coordinates).

LatLonToScreen2D

public static final Annotation.AnnotationType LatLonToScreen2D

An alternative way to position a 2D screen annotation is to convert a latitude-longitude coordinate to a screen coordinate, and use that screen coordinate to position a screen annotation. This is how LatLonToScreen2D annotations work. As the map is manipulated or the camera is moved, the screen annotation is moved around to match the latitude-longitude coordinate it was given. Unlike viewer-facing annotations, they are always the same size on the screen, and they always appear on top of everything rendered in the map.

Method Detail

values

public static Annotation.AnnotationType[] 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 (Annotation.AnnotationType c : Annotation.AnnotationType.values())
    System.out.println(c);

Returns:

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

valueOf

public static Annotation.AnnotationType 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
