  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[].

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

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)

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.
