com.intellij.util.containers.ConcurrentPackedBitsArray

public class ConcurrentPackedBitsArray
extends java.lang.Object

Packs the specified number of bits (1..32) into a chunk which stored in array and allows to get and set these bits atomically. Useful for storing related flags together. Guarantees are similar to ConcurrentBitSet, only for bit chunk instead of bit.
