Interface HallTransition

All Known Implementing Classes:

HallTransitionImpl

public interface HallTransition

Method Summary

float	getPosition() Get the position (in mm) where the transition occurred
float	getRelPosition() Get the relative position (0 - 1) where the transition occurred
int	getSensorId() Get the id of the Hall Sensor
long	getTransitionTime() Get the Epoch microseconds when the transition occurred.
boolean	isOpen() Check if the sensor is open after the transition.
boolean	isReverse() Check if the motion was in the reverse direction, in shutter coordinates.

Method Detail

getTransitionTime

long getTransitionTime()

Get the Epoch microseconds when the transition occurred.

getSensorId

int getSensorId()

Get the id of the Hall Sensor

isOpen

boolean isOpen()

Check if the sensor is open after the transition. Open is the state when no actuating magnet is near the sensor. The sensor closes and re-opens as a magnet moves past it.

isReverse

boolean isReverse()

Check if the motion was in the reverse direction, in shutter coordinates.

getPosition

float getPosition()

Get the position (in mm) where the transition occurred

getRelPosition

float getRelPosition()

Get the relative position (0 - 1) where the transition occurred
