  • Method Summary

    Modifier and Type
    Method
    Description
    static SegmentKey
    decode(byte[] b)
    Key decode in Yamcs starting with 5.10 - we use the invertSign for the timestamps in order for the negative times to sort before the positive ones in the archive
    static SegmentKey
    decodeV0(byte[] b)
    Version 0 is prior to Yamcs 5.10 when the negative times were not sorting properly
    byte[]
    encode()
    Key encode in Yamcs starting with 5.10 - we use the invertSign for the timestamps in order for the negative times to sort before the positive ones in the archive
    static byte[]
    encode(int parameterId, int parameterGroupId, long segmentStart, byte type)
    Key encode in Yamcs starting with 5.10 - we use the invertSign for the timestamps in order for the negative times to sort before the positive ones in the archive
    byte[]
    encodeV0()
    Version 0 is prior to Yamcs 5.10 when the negative times were not sorting properly
