java.lang.Object

com.ibm.icu.text.AlphabeticIndex.ImmutableIndex<V>

Type Parameters:

V - The Record value type is unused. It can be omitted for this class if it was omitted for the AlphabeticIndex that built it.

All Implemented Interfaces:

Iterable<AlphabeticIndex.Bucket<V>>

Enclosing class:

AlphabeticIndex<V>

public static final class AlphabeticIndex.ImmutableIndex<V>
extends Object
implements Iterable<AlphabeticIndex.Bucket<V>>

Immutable, thread-safe version of AlphabeticIndex. This class provides thread-safe methods for bucketing, and random access to buckets and their properties, but does not offer adding records to the index.
