public class IntRange extends AbstractList<Integer> implements Range<Integer>
This class is a copy of
ObjectRange optimized for int. If you make any
changes to this class, you might consider making parallel changes to ObjectRange.modCount| Modifier | Constructor and Description |

getFromInt()
Gets the 'from' value as an integer.

The upper value in the range.
|

getToInt()
Gets the 'to' value as an integer.

int to)
IntRange. If from is greater
than to, a reverse range is created with
from and to swapped.from - the first number in the range.to - the last number in the range.IllegalArgumentException - if the range would contain more than
Integer.MAX_VALUE values.protected IntRange(int from,
int to,
boolean reverse)
IntRange.from - the first value in the range.to - the last value in the range.reverse - true if the range should count from
to to from.IllegalArgumentException - if from is greater than to.public boolean equals(Object that)
AbstractList.equals(Object) if that is anything
other than an IntRange.
It is not necessary to override hashCode, as
AbstractList.hashCode() provides a suitable hash code.Note that equals is generally handled by
DefaultGroovyMethods.equals(List,List)
instead of this method.equals in interface Collection<Integer>equals in interface List<Integer>equals in class AbstractList<Integer>that - the object to comparetrue if the objects are equalpublic boolean equals(IntRange that)
