Method Details

readout

public Double readout()
               throws DeviceException

Description copied from interface: Detector

Returns the latest data collected. The size of the Object returned must be consistent with the values returned by getDataDimensions and getExtraNames.

If LocalProperties.GDA_SCAN_CONCURRENTSCAN_READOUT_CONCURRENTLY is true then motors may be moved while the detector readouts. The value returned must not be effected by any concurrent motor or shutter movements. See Detector.waitWhileBusy() and ConcurrentScan. Readout must block until the detector is ready to respond quickly to Detector.collectData() again.

Specified by:

readout in interface Detector

Returns:

the data collected

Throws:

DeviceException

getscalerListName

public String getscalerListName()

setscalerListName

public void setscalerListName(String[] scalerName)

getQexafsXmap

public BufferedDetector getQexafsXmap()

setQexafsXmap

public void setQexafsXmap(BufferedDetector qxmap)

getQexafsScaler

public BufferedScaler getQexafsScaler()

setQexafsScaler

public void setQexafsScaler(BufferedScaler scaler)

configure

public void configure()

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

clearMemory

public void clearMemory()
                 throws DeviceException

Description copied from interface: BufferedDetector

Clears the detector memory

Specified by:

clearMemory in interface BufferedDetector

Throws:

DeviceException

readAllFrames

public Object[] readAllFrames()
                       throws DeviceException

Description copied from interface: BufferedDetector

An array of the data from the detector. Each element is one frame of data.

Specified by:

readAllFrames in interface BufferedDetector

Returns:

Object

Throws:

DeviceException

readFrames

public Object[] readFrames(int startFrame,
 int finalFrame)
                    throws DeviceException

Description copied from interface: BufferedDetector

An array of the data from the detector. Each element is one frame of data. The first frame is 0.

Specified by:

readFrames in interface BufferedDetector

Parameters:

startFrame -

finalFrame -

Returns:

Object

Throws:

DeviceException

getContinuousParameters

public ContinuousParameters getContinuousParameters()
                                             throws DeviceException

Specified by:

getContinuousParameters in interface BufferedDetector

Returns:

ContinuousParameters

Throws:

DeviceException

getNumberFrames

public int getNumberFrames()
                    throws DeviceException

Specified by:

getNumberFrames in interface BufferedDetector

Returns:

number of frames of data in memory which have been collected

Throws:

DeviceException

isContinuousMode

public boolean isContinuousMode()
                         throws DeviceException

Specified by:

isContinuousMode in interface BufferedDetector

Returns:

true if the detector is ready to accept trigger pulses

Throws:

DeviceException

maximumReadFrames

public int maximumReadFrames()
                      throws DeviceException

Description copied from interface: BufferedDetector

As certain detectors may cause memory issues if too many frames are attempted to be read in one go, this is the maximum for this detector based on its current configuration (i.e. after setContinuousMode(True) has been called.

The lowest value returned from any of the detectors in a continuous scan will be the limit set.

If there is no limit then this method should return Integer.MAX_VALUE.

Specified by:

maximumReadFrames in interface BufferedDetector

Returns:

int - the maximum number of frames which should be read at any one time from this detector

Throws:

DeviceException

setContinuousMode

public void setContinuousMode(boolean on)
                       throws DeviceException

Description copied from interface: BufferedDetector

When in slave mode the detector will be triggered by an external signal to collect each frame of data.

Specified by:

setContinuousMode in interface BufferedDetector

Parameters:

on -

Throws:

DeviceException

setContinuousParameters

public void setContinuousParameters(ContinuousParameters parameters)
                             throws DeviceException

Description copied from interface: BufferedDetector

Sets the parameters which define the continuous movement to use

Specified by:

setContinuousParameters in interface BufferedDetector

Parameters:

parameters -

Throws:

DeviceException

collectData

public void collectData()
                 throws DeviceException

Description copied from interface: Detector

Tells the detector to begin to collect a set of data, then returns immediately. Should cause the hardware to start collecting immediately: if there is any delay then detectors used in the same scan would collect over different times when beam conditions may differ.

Specified by:

collectData in interface Detector

Throws:

DeviceException

createsOwnFiles

public boolean createsOwnFiles()
                        throws DeviceException

Description copied from interface: Detector

Returns a value which indicates whether the detector creates its own files. If it does (return true) the readout() method returns the name of the latest file created as a string. If it does not (return false) the readout() method will return the data directly.

Specified by:

createsOwnFiles in interface Detector

Returns:

true if readout() returns filenames

Throws:

DeviceException

getDescription

                      throws DeviceException

getDescription in interface Detector

Overrides:

getDescription in class DetectorBase

A description of the detector.
