Field Details

simulate

public boolean simulate

If true simulate a move when asked to move.

Constructor Details

DummyTrajectoryMoveController

public DummyTrajectoryMoveController()

Method Details

toString

public String toString()

Overrides:

toString in class Object

getNumberAxes

public int getNumberAxes()

Description copied from interface: TrajectoryMoveController

Get the number of axes configured on the controller. This may be less than the maximum number the controller supports,

Specified by:

getNumberAxes in interface TrajectoryMoveController

Returns:

number of configured axes.

stopAndReset

public void stopAndReset()

Description copied from interface: ContinuousMoveController

Stop a move if one is in progress and then reset the controller.

Specified by:

stopAndReset in interface ContinuousMoveController

addPoint

public void addPoint(Double[] point)
              throws DeviceException

Description copied from interface: TrajectoryMoveController

Called in sequence specifies the trajectory over all axes point by point. Alternatively use TrajectoryMoveController.setAxisTrajectory(int, double[]).

Specified by:

addPoint in interface TrajectoryMoveController

Parameters:

point - Array with a value for each axis. If an axis value is null null, indicating this axis is not to be used, then all positions for this axis must also be null.

Throws:

DeviceException

getLastPointAdded

public Double[] getLastPointAdded()
                           throws DeviceException

Description copied from interface: TrajectoryMoveController

Return the last point added.

Specified by:

getLastPointAdded in interface TrajectoryMoveController

Returns:

the last point added, or null if no points have been added or TrajectoryMoveController.setAxisTrajectory(int, double[]) has been used to configure the controller.

Throws:

DeviceException

prepareForMove

public void prepareForMove()
                    throws DeviceException

Description copied from interface: ContinuousMoveController

Prepare the already configured controller to move, waiting until ready. Normally this should move motors to the start position.

Specified by:

prepareForMove in interface ContinuousMoveController

Throws:

DeviceException

startMove

public void startMove()

Description copied from interface: ContinuousMoveController

Start the prepared move and return immediately.

Specified by:

startMove in interface ContinuousMoveController

isMoving

public boolean isMoving()

Description copied from interface: ContinuousMoveController

Check if the controller is moving axes.

Specified by:

isMoving in interface ContinuousMoveController

Returns:

true if moving.

waitWhileMoving

public void waitWhileMoving()
                     throws DeviceException,
InterruptedException

Description copied from interface: ContinuousMoveController

Wait until the controller has completed moving axes

Specified by:

waitWhileMoving in interface ContinuousMoveController

Throws:

InterruptedException

DeviceException

getNumberTriggers

public int getNumberTriggers()

Specified by:

getNumberTriggers in interface HardwareTriggerProvider

getTotalTime

public double getTotalTime()
                    throws DeviceException

Specified by:

getTotalTime in interface HardwareTriggerProvider

Throws:

DeviceException

setTriggerPeriod

public void setTriggerPeriod(double seconds)
                      throws DeviceException

Specified by:

setTriggerPeriod in interface HardwareTriggerProvider

Throws:

DeviceException

setTriggerDeltas

public void setTriggerDeltas(double[] triggerDeltas)

Description copied from interface: TrajectoryMoveController

Set a profile of potentially non-uniformly spaced trigger times. May not be supported by all controllers. Alternatively use HardwareTriggerProvider.setTriggerPeriod(double).

Specified by:

setTriggerDeltas in interface TrajectoryMoveController

Parameters:

triggerDeltas -

getPointsList

public Vector<Double[]> getPointsList()

setAxisTrajectory

public void setAxisTrajectory(int axisIndex,
 double[] trajectory)
                       throws DeviceException

Description copied from interface: TrajectoryMoveController

Set the entire trajectory for one axis. Alternatively use TrajectoryMoveController.addPoint(Double[]).

Specified by:

setAxisTrajectory in interface TrajectoryMoveController

Parameters:

axisIndex -

trajectory -

Throws:

DeviceException

setNumberAxes

public void setNumberAxes(int numberAxes)

readActualPositionsFromHardware

public List<double[]> readActualPositionsFromHardware()
