IntRange (Groovy 4.0.5)

groovy.lang.IntRange

All Implemented Interfaces and Traits:

Range, Serializable
```
public class IntRange
extends AbstractList
implements Range, Serializable
```
Represents a list of Integer objects starting at and potentially including a specified from value up (or down) to and potentially including a given to value.
Instances of this class may be either inclusive aware or non-inclusive aware. See the relevant constructors for creating each type. Inclusive aware IntRange instances are suitable for use with Groovy's range indexing - in particular if the from or to values might be negative. This normally happens underneath the covers but is worth keeping in mind if creating these ranges yourself explicitly.
Note: the design of this class might seem a little strange at first. It contains Boolean flags, inclusiveLeft and inclusiveRight, which can be true, false or null. This design is for backwards compatibility reasons. Groovy uses this class under the covers to represent range indexing, e.g. someList[x..y] and someString[x..<y]. In early versions of Groovy the ranges in these expressions were represented under the covers by the new IntRange(x, y) and new IntRange(x, y-1). This turns out to be a lossy abstraction when x and/or y are negative values. Now the latter case is represented by new IntRange(false, x, y).
Note: 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.

- Constructor Detail
  - public IntRange(int from, int to)
    
    Creates a new non-inclusive aware 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 Integer.MAX_VALUE values.
    
    Parameters:
    from - the first number in the range.
    to - the last number in the range.
  - public IntRange(boolean inclusiveRight, int from, int to)
    
    Creates a new inclusive aware IntRange.
    Parameters:
    from - the first value in the range.
    to - the last value in the range.
    inclusiveRight - true if the to value is included in the range.
  - public IntRange(boolean inclusiveLeft, boolean inclusiveRight, int from, int to)
    
    Creates a new inclusive aware IntRange
    Parameters:
    inclusiveLeft - true if the from value is included in the range.
    inclusiveRight - true if the to value is included in the range.
    from - the first value in the range.
    to - the last value in the range.
- Method Detail
  - <T extends Number & Comparable> public NumberRange by(T stepSize)
    
    Creates a new NumberRange with the same from and to as this IntRange but with a step size of stepSize.
    Parameters:
    stepSize - the desired step size
    Returns:
    a new NumberRange

  - @Override
    public boolean containsAll(Collection other)
  - @Override
    public boolean containsWithinBounds(Object o)
  - @Override
    public boolean equals(Object that)
    
    Determines if this object is equal to another object. Delegates to AbstractList.equals 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 instead of this method.
    Parameters:
    that - the object to compare
    Returns:
    true if the objects are equal
  - 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
  - @Override
    public Integer get(int index)
  - @Override
    public Integer getFrom()
  - public int getFromInt()
    
    Gets the 'from' value as a primitive integer.
    Returns:
    the 'from' value as a primitive integer.
  - public Boolean getInclusive()
    
    Returns the same as getInclusiveRight, kept here for backwards compatibility.
  - public Boolean getInclusiveLeft()
    
    Returns the inclusiveLeft flag. Null for non-inclusive aware ranges or non-null for inclusive aware ranges.
  - public Boolean getInclusiveRight()
    
    Returns the inclusiveRight flag. Null for non-inclusive aware ranges or non-null for inclusive aware ranges.
  - @Override
    public Integer getTo()
  - public int getToInt()
    
    Gets the 'to' value as a primitive integer.
    Returns:
    the 'to' value as a primitive integer.

  - @Override
    public List<Integer> subList(int fromIndex, int toIndex)
  - public RangeInfo subListBorders(int size)
    
    A method for determining from and to information when using this IntRange to index an aggregate object of the specified size. Normally only used internally within Groovy but useful if adding range indexing support for your own aggregates.
    Parameters:
    size - the size of the aggregate being indexed
    Returns:
    the calculated range information (with 1 added to the to value, ready for providing to subList
