extends ImmutableIterator[Nothing] with Product
Method Summary
def hasNext : Boolean

def next : Nothing
returns the next element and immutable iterator as a pair.
override def productArity : Int
return k for a product A(x_1,...,x_k)
override def productElement (arg0 : Int) : Any
for a product A(x_1,...,x_k), returns x_(n+1) for 0 <= n < k
override def productPrefix : java.lang.String
By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.
