public class NumberRange extends AbstractList implements Range, Serializable
Represents an immutable list of Numbers from a value to a value with a particular step size. In general, it isn't recommended using a NumberRange as a key to a map. The range 0..3 is deemed to be equal to 0.0..3.0 but they have different hashCode values, so storing a value using one of these ranges couldn't be retrieved using the other.

public NumberRange |
by(T stepSize) For a NumberRange with step size 1, creates a new NumberRange with the same from and to as this NumberRange
but with a step size of stepSize . |

public boolean |
contains(Object value) iterates over all values and returns true if one value matches. |
|
public boolean |
containsWithinBounds(Object value) Checks whether a value is between the from and to values of a Range |
|
public boolean |
equals(Object that) An object is deemed equal to this NumberRange if it represents a List of items and those items equal the list of discrete items represented by this NumberRange. |
|
public boolean |
fastEquals(NumberRange that) Compares a NumberRange to another NumberRange using only a strict comparison of the NumberRange properties. |

value
- the value of interestAn object is deemed equal to this NumberRange if it represents a List of items and those items equal the list of discrete items represented by this NumberRange.

if the specified object is equal to this NumberRangeCompares a NumberRange to another NumberRange using only a strict comparison of the NumberRange properties. This won't return true for some ranges which represent the same discrete items, use equals instead for that but will be much faster for large lists.

{@inheritDoc}
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.
