Class PGSegment

java.lang.Object

org.yamcs.parameterarchive.PGSegment

public class PGSegment
extends Object

Parameter Group segment - keeps references to Time and Value segments for a given parameter group and segment. This class is used during the parameter archive buildup - it uses GenericValueSegment to store any kind of Value - once the segment is full, the consolidate method will turn each GenericValueSegment into an storage optimised one.
