public class ExposureCount
extends AbstractRemoteParameter
implements ErrorDependingParameter, StatePreserving, Reloadable

This parameter provides the running number of an exposure within a target. It can be used to get different file-names per exposure on the same Unique.

We are not allowed to change any properties.

Method Summary

Object	get() Gets the current unique name identifier.
Object	getForError(ErrorEvent ee) Querying the unique parameter for an error returns the current unique number, advancing is only done by registering.
String	getUniqueExposure() The exposure number as an extension.
void	init() We scout for a file that hold the last unique values.
boolean	preserve() On exit, we save our current state if the serialize property is set.
void	registerError(ErrorEvent ee) If the error registered is a TargetPicked, we advance the unique number.
double	rescanned(String key, String old, String newval) We throw an illegal argument exception if export port changed
boolean	restore() We restore our old value by reading the last date and target count from a serialization file.
Object	set(Object val) Setting the unique number is only allowed vai a call to next, therefore this method throws an UnsupportedOperationException.

Constructor Detail

ExposureCount

public ExposureCount(Map<String,String> prop)
              throws RemoteException

We are not allowed to change any properties.

Throws:

RemoteException

Method Detail

init

public void init()

We scout for a file that hold the last unique values. If this is not present or given, we use the current date and zero.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractRemoteParameter

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

We throw an illegal argument exception if export port changed

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractRemoteParameter

restore

public boolean restore()

We restore our old value by reading the last date and target count from a serialization file.

Specified by:

restore in interface Preserving

Returns:

False, if restoring the value was not possible.

preserve

public boolean preserve()

On exit, we save our current state if the serialize property is set. First the date, then the targetnumber is writtn.

Specified by:

preserve in interface Preserving

Returns:

false, if preserving the current state was not possible

getUniqueExposure

public String getUniqueExposure()

The exposure number as an extension.

get

public Object get()

Gets the current unique name identifier.

Specified by:

get in interface Parameter

set

public Object set(Object val)
           throws UnsupportedOperationException

Setting the unique number is only allowed vai a call to next, therefore this method throws an UnsupportedOperationException.

Specified by:

set in interface Parameter

Returns:

The previous value of this parameter.

Throws:

UnsupportedOperationException - If this parameter is read-only.

registerError

public void registerError(ErrorEvent ee)

If the error registered is a TargetPicked, we advance the unique number.

Specified by:

registerError in interface ErrorDependingParameter

getForError

public Object getForError(ErrorEvent ee)

Querying the unique parameter for an error returns the current unique number, advancing is only done by registering.

Specified by:

getForError in interface ErrorDependingParameter

Returns:

null, if not a TargetPicked, otherwise get()
