Constructor Detail

KvnGenerator

public KvnGenerator(Appendable output,
                    int paddingWidth,
                    String outputName,
                    double maxRelativeOffset,
                    int unitsColumn)

Simple constructor.

Parameters:

output - destination of generated output

paddingWidth - padding width for aligning the '=' sign (not counting the extra blank added before the '=' sign)

outputName - output name for error messages

maxRelativeOffset - maximum offset in seconds to use relative dates (if a date is too far from reference, it will be displayed as calendar elements)

unitsColumn - columns number for aligning units (if negative or zero, units are not output)
