      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[].

Field Detail

### EMPTY_INTS

    public static final int[] EMPTY_INTS

### ints

    public int[] ints

### offset

    public int offset

### length

    public int length

Constructor Detail

### IntsRef

    public IntsRef()

### IntsRef

    public IntsRef(int capacity)

### IntsRef

    public IntsRef(int[] ints,
                   int offset,
                   int length)

Method Detail

### clone

    public IntsRef clone()

  Overrides:
    `clone` in class `Object`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`

### equals

    public boolean equals(Object other)

  Overrides:
    `equals` in class `Object`

### intsEquals

    public boolean intsEquals(IntsRef other)

### compareTo

    public int compareTo(IntsRef other)

  Signed int order comparison

  Specified by:
    `compareTo` in interface `Comparable<IntsRef>`

### copyInts

    public void copyInts(IntsRef other)

### grow

    public void grow(int newLength)

  Used to grow the reference array. In general this should not be used as it does not take the offset into account.

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

### 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.
