java.lang.Object
org.elasticsearch.common.util.BitArray
All Implemented Interfaces:
java.io.Closeable, java.lang.AutoCloseable, Releasable
public final class BitArray
extends java.lang.Object
implements Releasable
A bit array that is implemented using a growing LongArray created from BigArrays. The underlying long array grows lazily based on the biggest index that needs to be set.
