HecPairedData follows the conventions of HecTimeSeries, where you use the function write() to store data and read() to retrieve data. The primary functions for HecPairedData are:

public int setDSSFileName (String dssFileName)
public int write (PairedDataContainer pairedDataContainer)
public int read(PairedDataContainer pairedDataContainer)
public void done()
JAVA

Zero is returned on a successful call and a large negative value for unsuccessful. Do not reuse objects or containers; create a new one for every write or read.
