Enum ARTrackingFailureReason

java.lang.Object

java.lang.Enum<ARTrackingFailureReason>

com.codename1.ar.ARTrackingFailureReason

All Implemented Interfaces:

Comparable<ARTrackingFailureReason>

public enum ARTrackingFailureReason
extends Enum<ARTrackingFailureReason>

Why an ARSession reports ARTrackingState#LIMITED or ARTrackingState#NOT_TRACKING. Useful for prompting the user, for example to move the device more slowly or to point it at a textured surface.

Enum Constant Summary

Enum Constants

Enum Constant	Description
EXCESSIVE_MOTION	The device is moving too fast for reliable tracking.
INITIALIZING	The session is still gathering its first observations; tracking quality improves as the user moves the device.
INSUFFICIENT_FEATURES	The camera sees too few visual features, for example a blank wall.
INSUFFICIENT_LIGHT	The scene is too dark for the camera to track features.
NONE	Tracking is not degraded.

Method Summary

Modifier and Type	Method	Description
static ARTrackingFailureReason	valueOf(String name)	Returns the enum constant of this type with the specified name.
static ARTrackingFailureReason[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Details

values

public static ARTrackingFailureReason[] values()

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

Returns:

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

valueOf

public static ARTrackingFailureReason 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
