          com.anwrt.commons.protocol.model.data.AwtDeltasVector

public class AwtDeltasVector
extends AwtData

Simple container where values are numerical data and only difference are stored. A coefficient factor can be applied.

values[0] = start* factor
values[i+1] = values[i] + factor*deltas[i]

Example : the following values {200 210 180 200} could be encoded as coded as:

• factor=1, start=200, deltas = { 10 -30 +20 }
• factor=10, start=20, deltas = {1 -3 +2}
