@ServiceInterface(AperturePositioner.class)
public final class PersistentEpicsAperturePositioner
extends EpicsSimplePositioner
implements AperturePositioner

Positioner whose positions correspond to the codes of each available aperture.

The positioner's positions are the codes of the available apertures. moveTo(Object) must be called with an aperture's code, and EpicsSimplePositioner.getPosition() returns an aperture code.

If the positioner's position is changed, an ApertureChangedEvent is sent as an event to observers.

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	getApertureCode()	Gets the currently selected aperture's code.
void	moveTo(Object position)	Trigger a move/operation and block until completion.
void	setApertureCode(String code)	Sets the currently selected aperture.

public PersistentEpicsAperturePositioner()

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 EpicsSimplePositioner

Throws:

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

moveTo

public void moveTo(Object position)
            throws DeviceException

Description copied from class: ScannableBase

Trigger a move/operation and block until completion. If this is overridden, asynchronousMoveTo must also be valid, and the externalToInternal conversion must be applied.

Specified by:

moveTo in interface Scannable

Overrides:

moveTo in class ScannableBase

Parameters:

position -

Throws:

DeviceException

setApertureCode

public void setApertureCode(String code)

Description copied from interface: AperturePositioner

Sets the currently selected aperture.

Specified by:

setApertureCode in interface AperturePositioner

getApertureCode

public String getApertureCode()

Description copied from interface: AperturePositioner

Gets the currently selected aperture's code.

Specified by:

getApertureCode in interface AperturePositioner
