Class TrajectoryScanPreparer

java.lang.Object
gda.factory.FindableBase
gda.scan.TrajectoryScanPreparer
All Implemented Interfaces:
Findable, org.springframework.beans.factory.InitializingBean
public class TrajectoryScanPreparer extends FindableBase implements org.springframework.beans.factory.InitializingBean
Epics controller for Trajectory scan. Contains getters, setters for accessing PVs for time, position, velocity mode, user mode arrays, etc. needed for setting up, building and executing a trajectory scan. Trajectories can also be built up in memory by using the functions addPointsToTrajectory(java.lang.Double[], java.lang.Double[], java.lang.Integer[]),
invalid reference 
#addSpectrumToTrajectory
, addPointsForTimingGroups(gda.scan.TurboXasMotorParameters) before sending to Epics using sendProfileValues().
