Method Details

asynchronousMoveTo

public void asynchronousMoveTo(Object externalPosition)
                        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 ScannableBase

Parameters:

externalPosition - 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()
               throws DeviceException

Description copied from interface: Scannable

Check if the Scannable is moving/operating.

Returns:

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

Throws:

DeviceException

getDetectorZ

public Scannable getDetectorZ()

setDetectorZ

public void setDetectorZ(ScannableMotor detectorZ)

getSampleZ

public Scannable getSampleZ()

setSampleZ

public void setSampleZ(ScannableMotor sampleZ)
