Method Detail

idn

public java.lang.String idn()

Returns:

the identification string, as returned by IDN?

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

doSetPosition

protected final void doSetPosition(double z)

Overrides:

doSetPosition in class DummyPositionControl

getActualPosition

public double getActualPosition()

Description copied from class: PositionControlAdapter

get the actual position of the device. Since the mechanical device needs some time to reach the position, getPosition() can be different from getActualPosition()

Specified by:

getActualPosition in interface PositionControl

Overrides:

getActualPosition in class DummyPositionControl

Returns:

the actual position

sleep

public void sleep()

Description copied from class: PositionControlAdapter

sleeps for the time needed to stabilize the position.

Specified by:

sleep in interface PositionControl

Overrides:

sleep in class DummyPositionControl

main

public static void main(java.lang.String[] args)
