java.lang.Objectorg.sump.analyzer.CapturedData
public class CapturedData
CapturedData encapsulates the data obtained by the analyzer during a single run. It also provides a method for saving the data to a file.
Data files will start with a header containing meta data marked by lines starting with ";". The actual readout values will follow after the header. A value is a single logic level measurement of all channels at a particular time. This means a value is 32bits long. The value is encoded in hex and each value is followed by a new line.
In the java code each value is represented by an integer.
