values - source values

DoubleData

public DoubleData(double[] values,
                  int sampleRate,
                  long firstSampleNumber)

Constructs a Data object with the given values, collect time, and first sample number.

Parameters:

values - the data values

sampleRate - the sample rate of the data

firstSampleNumber - the position of the first sample in the original data

DoubleData

public DoubleData(double[] values,
                  int sampleRate,
                  long collectTime,
                  long firstSampleNumber)
