hasOldHashFormat

public boolean hasOldHashFormat()

Returns:

boolean: true if old hash format, i.e. no position given, or all positions given as -1 (meaning not present in xml) Note that even if hasOldHashFormat is true, the keys of the hashtable will still be MixCascade.MixPosition objects, not Strings as in previous versions of this class

setValues

private void setValues(org.w3c.dom.Element element)
