Class MovementHistoryStatus

java.lang.Object

org.lsst.ccs.subsystems.shutter.status.MovementHistoryStatus

All Implemented Interfaces:

Serializable

public class MovementHistoryStatus
extends Object
implements Serializable

Used to publish motor position samples and Hall data after a blade set motion. Immutable.

Carrying out a command might require several blade set movements so there are two boolean flags defined to mark the first and last movements required for the command. If a command requires just a single movement then both flags will be set.
