Class DetectorReadout

java.lang.Object
gda.scan.DetectorReadout
All Implemented Interfaces:
Runnable
public abstract class DetectorReadout extends Object implements Runnable
Runnable that can be used to collect detector data in a background thread. It monitors the number of frames of detector data available using getNumAvailableFrames(), and when enough frames for a new spectrum are available, it collects the spectrum data and writes it to the Nexus file using collectData(). Refactored from inner class in TurboXasScan.
