Method Details

rawAsynchronousMoveTo

public void rawAsynchronousMoveTo(Object position)
                           throws DeviceException

Description copied from class: ScannableBase

[Consider abstract] Trigger a move/operation to an internal/hardware position and return immediately.

Overrides:

rawAsynchronousMoveTo in class ScannableBase

Parameters:

position - Position in its internal/hardware representation. e.g. with units and offsets removed

Throws:

DeviceException

See Also:

• asynchronousMoveTo

rawGetPosition

public Object rawGetPosition()
                      throws DeviceException

Description copied from class: ScannableBase

[Consider abstract] Read the position in its internal (user) representation.

Overrides:

rawGetPosition in class ScannableBase

Returns:

the value represented by this Scannable

Throws:

DeviceException

See Also:

• Scannable.getPosition()

isBusy

public boolean isBusy()
               throws DeviceException

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

Throws:

DeviceException

See Also:

• Scannable.isBusy()
