Method Details
-
collectData
Description copied from interface:DetectorTells 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
Description copied from interface:DetectorReturns 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
Description copied from interface:DetectorReturns 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_CONCURRENTLYis true then motors may be moved while the detector readouts. The value returned must not be effected by any concurrent motor or shutter movements. SeeDetector.waitWhileBusy()andConcurrentScan. Readout must block until the detector is ready to respond quickly toDetector.collectData()again.- Returns:
- the data collected
- Throws:
DeviceException
-
createsOwnFiles
Description copied from interface:DetectorReturns 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
- Specified by:
getDescriptionin interfaceDetector- Overrides:
getDescriptionin classDetectorBase- Returns:
- A description of the detector.
- Throws:
DeviceException
-
getDetectorID
- Specified by:
getDetectorIDin interfaceDetector- Overrides:
getDetectorIDin classDetectorBase- Returns:
- A identifier for this detector.
- Throws:
DeviceException
-
getDetectorType
- Specified by:
getDetectorTypein interfaceDetector- Overrides:
getDetectorTypein classDetectorBase- Returns:
- The type of detector.
- Throws:
DeviceException
-
getDataDimensions
Description copied from class:DetectorBaseDefault which should be overridden by subclasses.- Specified by:
getDataDimensionsin interfaceDetector- Overrides:
getDataDimensionsin classDetectorBase- Returns:
- the dimensions of the data object returned by the
Detector.readout()method - Throws:
DeviceException- See Also:
-
getValue
- Parameters:
_returnType-subField-- Returns:
- Object
- Throws:
DeviceException
-
setValue
- Parameters:
subField-position-- Throws:
DeviceException
