public class SimpleDummyNexusDetector
extends DummyDetector
implements NexusDetector

A very simple dummy NexusDetector that writes a single dataset consisting of .tif filenames (the .tif files themselves are not created). The use case for this detector is to simulate a bug that occurs due to the axis dataset being added, while the dataset itself is flattened to be scalar (or rather to have rank equal to the scan rank).

readout

public NexusTreeProvider 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.
