[Java] Class ObjectRange

groovy.lang.ObjectRange

All Implemented Interfaces and Traits:: Range

public class ObjectRange
extends AbstractList
implements Range

Represents an inclusive list of objects from a value to a value using comparators.

Note: This class is similar to IntRange. If you make any changes to this class, you might consider making parallel changes to IntRange.

Constructor and description
`ObjectRange (Comparable from, Comparable to)` Creates a new ObjectRange.
`ObjectRange (Comparable smaller, Comparable larger, boolean reverse)` Creates a new ObjectRange assumes smaller <= larger, else behavior is undefined.

Constructor Detail

public ObjectRange(Comparable from, Comparable to)

Creates a new ObjectRange. Creates a reversed range if from < to.

Parameters:: from - the first value in the range.; to - the last value in the range.

public ObjectRange(Comparable smaller, Comparable larger, boolean reverse)

Creates a new ObjectRange assumes smaller <= larger, else behavior is undefined. Caution: Prefer the other constructor when in doubt.

Optimized Constructor avoiding initial computation of comparison.

Method Detail

protected void checkBoundaryCompatibility()

throws IllegalArgumentException if to and from are incompatible, meaning they e.g. (likely) produce infinite sequences. Called at construction time, subclasses may override cautiously (using only members to and from).

protected int compareTo(Comparable first, Comparable second)

@Override public boolean contains(Object value)

Iterates over all values and returns true if one value matches.

See Also:: containsWithinBounds(Object)

@Override public boolean containsWithinBounds(Object value)

Checks whether a value is between the from and to values of a Range

Parameters:: value - the value of interest

Returns:: true if the value is within the bounds

protected Object decrement(Object value)

Decrements by one

Parameters:: value - the value to decrement

Returns:: the decremented value

public boolean equals(Object that)

public boolean equals(ObjectRange that)

Compares an ObjectRange to another ObjectRange.

Parameters:: that - the object to check equality with

Returns:: true if the ranges are equal

@Override public Comparable get(int index)

@Override public Comparable getFrom()

@Override public Comparable getTo()

protected Object increment(Object value)

Increments by one

Parameters:: value - the value to increment

Returns:: the incremented value

@Override public String inspect()

@Override public boolean isReverse()

@Override public Iterator<Comparable> iterator()

{@inheritDoc}

@Override public int size()

@Override public void step(int step, Closure closure)

@Override public List<Comparable> step(int step)

@Override public List<Comparable> subList(int fromIndex, int toIndex)

public String toString()
