Class IndexSequence

java.lang.Object
  org.infinispan.schematic.internal.document.IndexSequence

All Implemented Interfaces:

Iterable<String>, Collection<String>, Set<String>

public class IndexSequence
extends Object
implements Set<String>

An IndexSequence is a lightweight ordered sequence of string representing array indexes. It is lightweight because it shares and reuses the strings for indexes less than the maximum key count.

Since:

5.1

size

protected final int size

Constructor Detail

IndexSequence

public IndexSequence(int size)

Method Detail

indexesTo

public static Iterator<String> indexesTo(int size)

Obtain an iterator for the indexes up to the specified size.

Parameters:

size - the number of indexes

Returns:

the iterator of string indexes; never null

infiniteSequence

public static Iterator<String> infiniteSequence()

Obtain an iterator for the indexes up the largest integer. This is efficient, because it only builds strings as needed.

Returns:

the iterator of string indexes; never null
