IntegerRange	back to summary
public IntegerRange(int start, int end) Constructs a new IntegerRange object. The step will be set to -1 if end<start or to 1 otherwise. Parameters start:int the start value (inclusive) end:int the end value (inclusive) Annotations @Pure

IntegerRange	back to summary
public IntegerRange(int start, int end, int step) Constructs a new IntegerRange object. Parameters start:int the start value (inclusive) end:int the end value (inclusive if end-start%step == 0) step:int the increment Annotations @Pure

contains	back to summary
public boolean contains(int number) Checks whether this contains the given number, i.e. whether the iterator will yield the number. This is different from interval containment: `0..2.by(2)` will not contain 1. Parameters number:int the number to be checked for containment. Returns:boolean whether this sequence contains the given number or not. Annotations @Pure

getEnd	back to summary
public int getEnd() Returns:int the end value Annotations @Pure

getSize	back to summary
public int getSize() Returns the number of elements in this IntegerRange. That is not the length of the interval, but `(end-start)/step + 1`. Returns:int the number of elements in this IntegerRange. Annotations @Pure

getStart	back to summary
public int getStart() Returns:int the start value Annotations @Pure

getStep	back to summary
public int getStep() Returns:int the step value Annotations @Pure

iterator	back to summary
public ListIterator<Integer> iterator() Implements java.lang.Iterable.iterator. Doc from java.lang.Iterable.iterator. Returns an iterator over elements of type `T`. Returns:ListIterator<Integer> a read-only `ListIterator` for this. Annotations @Override @Pure

withStep	back to summary
public IntegerRange withStep(int step) Parameters step:int the step of the new range. Returns:IntegerRange a new IntegerRange with the given step. Annotations @Pure

Method Summary

Modifier and Type	Method and Description
public void	add(Integer e) Implements java.util.ListIterator.add. Inserts the specified element into the list (optional operation).
public boolean	hasNext() Implements java.util.ListIterator.hasNext. Returns `true` if this list iterator has more elements when traversing the list in the forward direction.
public boolean	hasPrevious() Implements java.util.ListIterator.hasPrevious. Returns `true` if this list iterator has more elements when traversing the list in the reverse direction.
public Integer	next() Implements java.util.ListIterator.next. Returns the next element in the list and advances the cursor position.
public int	nextIndex() Implements java.util.ListIterator.nextIndex. Returns the index of the element that would be returned by a subsequent call to `next`.
public Integer	previous() Implements java.util.ListIterator.previous. Returns the previous element in the list and moves the cursor position backwards.
public int	previousIndex() Implements java.util.ListIterator.previousIndex. Returns the index of the element that would be returned by a subsequent call to `previous`.
public void	remove() Implements java.util.ListIterator.remove. Removes from the list the last element that was returned by `next` or `previous` (optional operation).
public void	set(Integer e) Implements java.util.ListIterator.set. Replaces the last element returned by `next` or `previous` with the specified element (optional operation).

add back to summary

add	back to summary
public void add(Integer e) Implements java.util.ListIterator.add. Doc from java.util.ListIterator.add. Inserts the specified element into the list (optional operation). The element is inserted immediately before the element that would be returned by `next`, if any, and after the element that would be returned by `previous`, if any. (If the list contains no elements, the new element becomes the sole element on the list.) The new element is inserted before the implicit cursor: a subsequent call to `next` would be unaffected, and a subsequent call to `previous` would return the new element. (This call increases by one the value that would be returned by a call to `nextIndex` or `previousIndex`.) Annotations @Override

public void add(Integer e)

Implements java.util.ListIterator.add.

Doc from java.util.ListIterator.add.

Inserts the specified element into the list (optional operation). The element is inserted immediately before the element that would be returned by next, if any, and after the element that would be returned by previous, if any. (If the list contains no elements, the new element becomes the sole element on the list.) The new element is inserted before the implicit cursor: a subsequent call to next would be unaffected, and a subsequent call to previous would return the new element. (This call increases by one the value that would be returned by a call to nextIndex or previousIndex.)
