java.lang.Object
- org.apache.lucene.util.IntsRef

All Implemented Interfaces:

Cloneable, Comparable<IntsRef>
```
public final class IntsRef
extends Object
implements Comparable<IntsRef>, Cloneable
```
Represents int[], as a slice (offset + length) into an existing int[]. The ints member should never be null; use EMPTY_INTS if necessary.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Field Summary

Fields
Modifier and Type	Field	Description
`static int[]`	`EMPTY_INTS`	An empty integer array for convenience
`int[]`	`ints`	The contents of the IntsRef.
`int`	`length`	Length of used ints.
`int`	`offset`	Offset of first valid integer.

Constructor Summary

Constructors
Constructor	Description
`IntsRef()`	Create a IntsRef with `EMPTY_INTS`
`IntsRef(int capacity)`	Create a IntsRef pointing to a new array of size `capacity`.
`IntsRef(int[] ints, int offset, int length)`	This instance will directly reference ints w/o making a copy.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`IntsRef`	`clone()`	Returns a shallow clone of this instance (the underlying ints are not copied and will be shared by both the returned object and this object.
`int`	`compareTo(IntsRef other)`	Signed int order comparison
`static IntsRef`	`deepCopyOf(IntsRef other)`	Creates a new IntsRef that points to a copy of the ints from `other`
`boolean`	`equals(Object other)`
`int`	`hashCode()`
`boolean`	`intsEquals(IntsRef other)`
`boolean`	`isValid()`	Performs internal consistency checks.
`String`	`toString()`

- Method Detail
  - clone
```
public IntsRef clone()
```
    Returns a shallow clone of this instance (the underlying ints are not copied and will be shared by both the returned object and this object.

    Specified by:
    
    compareTo in interface Comparable<IntsRef>
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - deepCopyOf
```
public static IntsRef deepCopyOf(IntsRef other)
```
    Creates a new IntsRef that points to a copy of the ints from other
    The returned IntsRef will have a length of other.length and an offset of zero.
  - isValid
```
public boolean isValid()
```
    Performs internal consistency checks. Always returns true (or throws IllegalStateException)
