DeviceOrientation.Builder

public static final class DeviceOrientation.Builder extends Object

A builder for DeviceOrientation.

Public Constructor Summary

	Builder(float[] attitude, float headingDegrees, float headingErrorDegrees, long elapsedRealtimeNs) Constructs a new builder with required fields values.
	Builder(DeviceOrientation src) Constructs a new builder with values copied from the given `DeviceOrientation`.

Public Method Summary

DeviceOrientation	build() Builds a new `DeviceOrientation`.
DeviceOrientation.Builder	clearConservativeHeadingErrorDegrees() Resets the estimated conservative heading error (in degrees) in the reported heading of the device.
DeviceOrientation.Builder	setAttitude(float[] attitude) Sets the attitude of the device.
DeviceOrientation.Builder	setConservativeHeadingErrorDegrees(float conservativeHeadingErrorDegrees) Sets the conservative heading error (in degrees) in the reported heading (in the range [0, 180]).
DeviceOrientation.Builder	setElapsedRealtimeNs(long elapsedRealtimeNs) Sets the time (in nanoseconds) when this device orientation is estimated, in elapsed real-time since system boot.
DeviceOrientation.Builder	setHeadingDegrees(float headingDegrees) Sets the estimated heading of the device in degrees between [0, 360).
DeviceOrientation.Builder	setHeadingErrorDegrees(float headingErrorDegrees) Sets the estimated error in the reported heading of the device in degrees (in the range [0, 180]).

public Builder (DeviceOrientation src)

Constructs a new builder with values copied from the given DeviceOrientation.

Public Methods

public DeviceOrientation build ()

Builds a new DeviceOrientation.

public DeviceOrientation.Builder clearConservativeHeadingErrorDegrees ()

Resets the estimated conservative heading error (in degrees) in the reported heading of the device.

public DeviceOrientation.Builder setAttitude (float[] attitude)

Sets the attitude of the device. For more details see DeviceOrientation.getAttitude()

Parameters

attitude	float array of length 4 and corresponding to a quaternion in the order (x, y, z, w).

Throws

IllegalArgumentException	if `attitude` doesn't contain 4 items or contains a `NaN`.

public DeviceOrientation.Builder setConservativeHeadingErrorDegrees (float conservativeHeadingErrorDegrees)

Sets the conservative heading error (in degrees) in the reported heading (in the range [0, 180]).

Throws

IllegalArgumentException	if `conservativeHeadingErrorDegrees` is out of the allowed range

public DeviceOrientation.Builder setElapsedRealtimeNs (long elapsedRealtimeNs)

Sets the time (in nanoseconds) when this device orientation is estimated, in elapsed real-time since system boot.

Throws

IllegalArgumentException	if `elapsedRealtimeNs` is less than zero

public DeviceOrientation.Builder setHeadingDegrees (float headingDegrees)

Sets the estimated heading of the device in degrees between [0, 360). For further explanation see DeviceOrientation.getHeadingDegrees()

Throws

IllegalArgumentException	if `headingDegrees` is out of the allowed range

public DeviceOrientation.Builder setHeadingErrorDegrees (float headingErrorDegrees)

Sets the estimated error in the reported heading of the device in degrees (in the range [0, 180]). For further explanation see DeviceOrientation.getHeadingErrorDegrees().

Throws

IllegalArgumentException	if `headingErrorDegrees` is out of the allowed range
