public DummyControlPoint()

Method Details

getValue

public double getValue()
                throws DeviceException

Description copied from interface: ControlPoint

Returns the latest value observed by this Control Point.

Specified by:

getValue in interface ControlPoint

Returns:

the latest value of the monitor

Throws:

DeviceException

setValue

public void setValue(double target)
              throws DeviceException

Description copied from interface: ControlPoint

Set the target Control Point

Specified by:

setValue in interface ControlPoint

Parameters:

target - the target control point value

Throws:

DeviceException

asynchronousMoveTo

public void asynchronousMoveTo(Object position)
                        throws DeviceException

Description copied from class: ScannableBase

Trigger a move/operation and return immediately. Implementations of this method should be non-blocking to allow concurrent motion; the isBusy method will be used to determine when the move has completed. Converts the external (user) position to an internal position and passes this to rawAsynchronousMoveTo.

Specified by:

asynchronousMoveTo in interface Scannable

Overrides:

asynchronousMoveTo in class ScannableMotionBase

Parameters:

position - Position to move to should have an element for each input field.

Throws:

DeviceException

getPosition

public Object getPosition()
                   throws DeviceException

Description copied from class: ScannableBase

Returns the current position of the Scannable. Called by ConcurentScan at the end of the point. Reads an internal (hardware) position from rawGetPosition, converts this to an external (user) position and returns it.

Specified by:

getPosition in interface Scannable

Overrides:

getPosition in class ScannableBase

Returns:

Current position with an element for each input and extra field. null if their are no fields.

Throws:

DeviceException

isBusy

public boolean isBusy()

Description copied from class: ScannableMotionBase

Check if the Scannable is moving/operating.. Calls onto rawIsBusy for historical reasons, although there is currently no need for this.

Specified by:

isBusy in interface Scannable

Overrides:

isBusy in class ScannableMotionBase

Returns:

true - if operation carried out by moveTo has not completed yet
