Method Details

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.

Throws:

DeviceException

getStatus

public int getStatus()
              throws DeviceException

Description copied from interface: Detector

Returns the current collecting state of the device.

Returns:

BUSY if the detector has not finished the requested operation(s), IDLE if in an completely idle state and STANDBY if temporarily suspended.

Throws:

DeviceException

readout

public Object 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.

Returns:

the data collected

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.

Returns:

true if readout() returns filenames

Throws:

DeviceException

getDescription

public String getDescription()
                      throws DeviceException

Specified by:

getDescription in interface Detector

Overrides:

getDescription in class DetectorBase

Returns:

A description of the detector.

Throws:

DeviceException

getDetectorID

public String getDetectorID()
                     throws DeviceException

Specified by:

getDetectorID in interface Detector

Overrides:

getDetectorID in class DetectorBase

Returns:

A identifier for this detector.

Throws:

DeviceException

getDetectorType

public String getDetectorType()
                       throws DeviceException

Specified by:

getDetectorType in interface Detector

Overrides:

getDetectorType in class DetectorBase

Returns:

The type of detector.

Throws:

DeviceException

getDataDimensions

public int[] getDataDimensions()
                        throws DeviceException

Description copied from class: DetectorBase

Default which should be overridden by subclasses.

Specified by:

getDataDimensions in interface Detector

Overrides:

getDataDimensions in class DetectorBase

Returns:

the dimensions of the data object returned by the Detector.readout() method

Throws:

DeviceException

See Also:

• Detector.getDataDimensions()

getValue

public Object getValue(ReturnType _returnType,
 String subField)
                throws DeviceException

Parameters:

_returnType -

subField -

Returns:

Object

Throws:

DeviceException

setValue

public void setValue(String subField,
 Object position)
              throws DeviceException

Parameters:

subField -

position -

Throws:

DeviceException
