    Enum Constants
    Enum Constant and Description
    `IDENTITY_COMPARISONS` Indicates that referential-equality (== instead of .equals()) should be used when locating keys.

  - ### Method Summary

    All Methods Static Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `static ConcurrentReferenceHashMap.Option` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static ConcurrentReferenceHashMap.Option[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### 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 Detail

    - #### values

          public static ConcurrentReferenceHashMap.Option[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (ConcurrentReferenceHashMap.Option c : ConcurrentReferenceHashMap.Option.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static ConcurrentReferenceHashMap.Option valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
        `NullPointerException` - if the argument is null
