Constructor Summary

Constructors

Constructor and Description
Range(int fst, int ovr)
Range(int fst, int ovr, int step) The principal constructor for [fst, fst+step, fst+2*step, ...].
Range(Value.Int fst, Value.Int ovr)
Range(Value.Int fst, Value.Int ovr, Value.Int step)

Method Summary

Modifier and Type	Method and Description
void	advance() Advance past the current element -- there might or might not be any more; also see Series.hasSome().
int	elt_n() The current element's int "code".
Value.Int	elt() See elt_n().
boolean	hasSome() Is there at least a current element, (Series.elt())? Also see Series.hasNone().
int	position() What position in the Series are we at (starting at zero)? If Series.hasNone(), the series was finite and position() is now its length.
java.lang.String	toString() Return a short String description of 'this' Series, say for use in debugging.
