Class MagnetometerReading

java.lang.Object

com.gluonhq.charm.down.plugins.MagnetometerReading

public final class MagnetometerReading
extends java.lang.Object

Represents a reading taken from the MagnetometerService. By using a device's geomagnetic field sensor in combination with the device's accelerometer, three orientation angles (azimut, pitch and roll) can be determined

Since:

3.0.0

MagnetometerReading

public MagnetometerReading(double x,
                           double y,
                           double z,
                           double magnitude,
                           double yaw,
                           double pitch,
                           double roll)

Creates a new immutable Reading instance with the given x, y, z, magnitude values, and orientation angles.

Parameters:

x - The x value of the reading

y - The y value of the reading

z - The z value of the reading

magnitude - The magnitude of the reading

yaw - rotation about the -z axis

pitch - rotation about the x axis

roll - rotation about the y axis

Method Detail

getX

public double getX()

Returns the x value of the reading, microtesla units.

Returns:

The x value of the reading.

getY

public double getY()

Returns the y value of the reading, microtesla units

Returns:

The y value of the reading.

getZ

public double getZ()

Returns the z value of the reading, microtesla units

Returns:

The z value of the reading.

getMagnitude

public double getMagnitude()

Returns the magnitude of the reading, microtesla units

Returns:

The magnitude of the reading.

getYaw

public double getYaw()

Yaw (rotation about the -z axis, radians). This is the angle between the device's current compass direction and the magnetic north. Top edge of the device faces magnetic N: 0 degrees, S: Pi, E: Pi/2, W: -Pi/2. The range of values is -Pi to Pi.

Returns:

yaw angle

getPitch

public double getPitch()

Pitch (rotation about the x axis, radians). This is the angle between a plane parallel to the device's screen and a plane parallel to the ground. Tilting the top edge of the device toward the ground: the pitch angle becomes positive. Tilting the top edge of the device away from the ground: the pitch angle to become negative. The range of values is -Pi to Pi.

Returns:

pitch angle

getRoll

public double getRoll()

Roll (rotation about the y axis, radians). This is the angle between a plane perpendicular to the device's screen and a plane perpendicular to the ground. Tilting to the left the device toward the ground, the roll angle becomes positive. Tilting to the right the device toward the ground, the roll angle to become negative. The range of values is -Pi to Pi.

Returns:

roll angle

getAzimuth

public double getAzimuth()

Azimuth (rotation about the -z axis, degrees). Returns the compass reading, represented as a value between 0 and 359.99, where 0 is the magentic north.

Returns:

The current compass reading in degrees.
