java.lang.Object

org.yamcs.parameterarchive.ParameterValueSegment

org.yamcs.parameterarchive.SynchronizedParameterValueSegment

public class SynchronizedParameterValueSegment
extends ParameterValueSegment

Parameter value segment used by the realtime filler which is also used during retrieval.

We use a read-write lock in order to avoid retrieval reading inconsistent data
