Class JDXDecompressor

java.lang.Object
jspecview.source.JDXDecompressor
All Implemented Interfaces:
Iterator<Double>
public class JDXDecompressor extends Object implements Iterator<Double>
JDXDecompressor contains static methods to decompress the data part of JCAMP-DX spectra that have been compressed using DIF, FIX, SQZ or PAC formats. If you wish to parse the data from XY formats see Coordinate.parseDSV(java.lang.String, double, double)
