  - ### IDENTITY_COMPARISONS

    public static final ConcurrentReferenceHashMap.Option IDENTITY_COMPARISONS
    Indicates that referential-equality (== instead of .equals()) should be used when locating keys. This offers similar behavior to `IdentityHashMap`

- ## Method Details

  - ### values

    public static ConcurrentReferenceHashMap.Option[] values()
    Returns an array containing the constants of this enum class, in the order they are declared.
    Returns:
      an array containing the constants of this enum class, in the order they are declared

  - ### valueOf

    public static ConcurrentReferenceHashMap.Option valueOf(String name)
    Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
    Parameters:
      `name` - the name of the enum constant to be returned.
    Returns:
      the enum constant with the specified name
    Throws:
      `IllegalArgumentException` - if this enum class has no constant with the specified name
      `NullPointerException` - if the argument is null
