All Implemented Interfaces:

Device, Scannable, Configurable, Findable, gda.observable.IObservable

@ServiceInterface(Scannable.class)
public class PositionerDeterminedScannable
extends ScannableBase

The delegate Scannable is determined by the position of an EnumPositioner. An observer is attached to the positioner to update the delegate selection as the positioner moves.

Method Summary

Modifier and Type	Method	Description
void	configure()	Default implementation for classes that do not have to do any specific configuration. Classes that do their own configuration should *not* call this superclass function, as it may cause the object to appear configured before it really is.
String[]	getOutputFormat()	Returns an array of strings which are the format strings to use when pretty printing parts of the output
boolean	isBusy()	Check if the Scannable is moving/operating.
void	rawAsynchronousMoveTo(Object position)	[Consider abstract] Trigger a move/operation to an internal/hardware position and return immediately.
Object	rawGetPosition()	[Consider abstract] Read the position in its internal (user) representation.

Method Details

configure

public void configure()
               throws FactoryException

Description copied from class: ConfigurableBase

Default implementation for classes that do not have to do any specific configuration.
Classes that do their own configuration should *not* call this superclass function, as it may cause the object to appear configured before it really is.

Specified by:

configure in interface Configurable

Overrides:

configure in class ConfigurableBase

Throws:

FactoryException - if there is an error in configuration e.g. required variable not set or cannot connect to device

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

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()

getOutputFormat

public String[] getOutputFormat()

Description copied from interface: Scannable

Returns an array of strings which are the format strings to use when pretty printing parts of the output

Specified by:

getOutputFormat in interface Scannable

Overrides:

getOutputFormat in class ScannableBase

Returns:

string array
