          groovy.lang.IntRange
All Implemented Interfaces:
Range
public class IntRange
extends java.util.AbstractList

Represents a list of Integer objects from a specified int up (or down) to and including a given to.

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.

Method Detail

IntRange

public java.lang.Object IntRange(int from, int to)
Creates a new IntRange. If from is greater than to, a reverse range is created with from and to swapped.
throws:
IllegalArgumentException if the range would contain more than java.lang.Integer#MAX_VALUE values.
Parameters:
from - the first number in the range.
to - the last number in the range.

IntRange

protected java.lang.Object IntRange(int from, int to, boolean reverse)
Creates a new IntRange.
throws:
IllegalArgumentException if from is greater than to.
Parameters:
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.

contains

public boolean contains(java.lang.Object value)
{@inheritDoc}

containsAll

public boolean containsAll(java.util.Collection other)
{@inheritDoc}

containsWithinBounds

public boolean containsWithinBounds(java.lang.Object o)

equals

public boolean equals(java.lang.Object that)
Determines if this object is equal to another object. Delegates to java.util.AbstractList#equals(java.lang.Object) if that is anything other than an IntRange.

It is not necessary to override hashCode, as java.util.AbstractList#hashCode() provides a suitable hash code.

Note that equals is generally handled by DefaultGroovyMethods.equals instead of this method.

Parameters:
that - the object to compare
Returns:
true if the objects are equal

equals

public boolean equals(IntRange that)
Compares an IntRange to another IntRange.
Parameters:
that - the object to compare for equality
Returns:
true if the ranges are equal

get

public java.lang.Integer get(int index)
{@inheritDoc}

getFrom

public java.lang.Comparable getFrom()
{@inheritDoc}

getFromInt

public int getFromInt()
Gets the 'from' value as an integer.
Returns:
the 'from' value as an integer.

getTo

public java.lang.Comparable getTo()
{@inheritDoc}

getToInt

public int getToInt()
Gets the 'to' value as an integer.
Returns:
the 'to' value as an integer.

inspect

public java.lang.String inspect()
{@inheritDoc}

isReverse

public boolean isReverse()
{@inheritDoc}

iterator

public java.util.Iterator iterator()
{@inheritDoc}

size

public int size()
{@inheritDoc}

step

public void step(int step, Closure closure)
{@inheritDoc}

step

public java.util.List step(int step)
{@inheritDoc}

subList

public java.util.List subList(int fromIndex, int toIndex)
{@inheritDoc}

toString

public java.lang.String toString()
{@inheritDoc}
