Class IntRange

java.lang.Object
  java.util.AbstractCollection
      java.util.AbstractList
          groovy.lang.IntRange
All Implemented Interfaces:
Range
class IntRange
extends 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 def 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.
param:
from the first number in the range.
param:
to the last number in the range.
throws:
IllegalArgumentException if the range would contain more than Integer#MAX_VALUE values.

IntRange

protected def IntRange(int from, int to, boolean reverse)
Creates a new IntRange.
param:
from the first value in the range.
param:
to the last value in the range.
param:
reverse true if the range should count from to to from.
throws:
IllegalArgumentException if from is greater than to.

contains

public boolean contains(Object value)
{@inheritDoc}

containsAll

public boolean containsAll(Collection other)
{@inheritDoc}

containsWithinBounds

public boolean containsWithinBounds(Object o)

equals

public boolean equals(Object that)
Determines if this object is equal to another object. Delegates to AbstractList#equals(Object) if that is anthing 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 instead of this method.

param:
that the object to compare
return:
true if the objects are equal

equals

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

get

public Integer get(int index)
{@inheritDoc}

getFrom

public Comparable getFrom()
{@inheritDoc}

getFromInt

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

getTo

public Comparable getTo()
{@inheritDoc}

getToInt

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

inspect

public String inspect()
{@inheritDoc}

isReverse

public boolean isReverse()
{@inheritDoc}

iterator

public Iterator iterator()
{@inheritDoc}

size

public int size()
{@inheritDoc}

step

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

step

public List step(int step)
{@inheritDoc}

subList

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

toString

public String toString()
{@inheritDoc}
