Constructor Detail

Def Detail

Create an iterator with elements e_n+1 = e_n + 1 where e₀ = lo.

def from (lo: scala.Int, step: scala.Function1[scala.Int, scala.Int]): scala.Iterator[scala.Int]

Create an iterator with elements e_n+1 = step(e_n) where e₀ = lo.

Create an iterator with elements e_n+1 = e_n + step where e₀ = lo.

def fromArray [a](xs: scala.Array[a], start: scala.Int, length: scala.Int): scala.Iterator[a]

Create an iterator with elements e_n+1 = e_n + 1 where e₀ = lo and e_i < end.

def range (lo: scala.Int, end: scala.Int, step: scala.Function1[scala.Int, scala.Int]): scala.Iterator[scala.Int]

Create an iterator with elements e_n+1 = step(e_n) where e₀ = lo and e_i < end.

def range (lo: scala.Int, end: scala.Int, step: scala.Int): scala.Iterator[scala.Int]

Create an iterator with elements e_n+1 = e_n + step where e₀ = lo and e_i < end.

Parameters:: lo - the start value of the iterator
Parameters:: end - the end value of the iterator
Parameters:: step - the increment value of the iterator (must be positive or negative)
Returns:: the iterator with values in range [lo;end).
