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	getControllerRecordName()	Gets the name of the controller record, e.g.
String	getCurrentPosition()
String[]	getPositions()	Returns an array of the positions which this device can be moved to.
String	getReadPV()
String	getSetPV()
String	getTargetPosition()
void	initializationCompleted()	Called when all critical channels are connected.
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.
void	setReadPV(String readPV)
void	setSetPV(String setPV)

EpicsAirBearingControl

public EpicsAirBearingControl()

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

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()

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

isBusy

public boolean isBusy()
               throws DeviceException

Description copied from interface: Scannable

Check if the Scannable is moving/operating.

Specified by:

isBusy in interface Scannable

Overrides:

isBusy in class EnumPositionerBase

Returns:

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

Throws:

DeviceException

getPositions

public String[] getPositions()
                      throws DeviceException

Description copied from interface: EnumPositioner

Returns an array of the positions which this device can be moved to.

Specified by:

getPositions in interface EnumPositioner

Overrides:

getPositions in class EnumPositionerBase

Returns:

an array of positions

Throws:

DeviceException

initializationCompleted

public void initializationCompleted()
                             throws InterruptedException,
DeviceException,
gov.aps.jca.TimeoutException,
gov.aps.jca.CAException

Description copied from interface: InitializationListener

Called when all critical channels are connected.

Specified by:

initializationCompleted in interface InitializationListener

Throws:

InterruptedException

DeviceException

gov.aps.jca.TimeoutException

gov.aps.jca.CAException

getReadPV

public String getReadPV()

setReadPV

public void setReadPV(String readPV)

getSetPV

public String getSetPV()

setSetPV

public void setSetPV(String setPV)

getTargetPosition

public String getTargetPosition()

getCurrentPosition

public String getCurrentPosition()

getControllerRecordName

public String getControllerRecordName()

Description copied from interface: ControllerRecord

Gets the name of the controller record, e.g. EPICS process variable name. For example, in NeXus this value can be written as the value of the controller_record field for the NXpositioner for the scannable.

Specified by:

getControllerRecordName in interface ControllerRecord

Returns:

controller record name
