8. #### abstract class MultiChoiceEnumeration extends Enumeration

   Each MultiChoiceSetting takes a MultiChoiceEnumeration as domain.

   Each MultiChoiceSetting takes a MultiChoiceEnumeration as domain. The enumeration may use the Choice class to define values, or simply use the default `Value` constructor:

   object SettingDomain extends MultiChoiceEnumeration { val arg1, arg2 = Value }

   Or

   object SettingDomain extends MultiChoiceEnumeration { val arg1 = Choice("arg1", "help") val arg2 = Choice("arg2", "help") }

   Choices with a non-empty `expandsTo` enable other options. Note that expanding choices are not present in the multiChoiceSetting.value set, only their expansion.

     MutableSettings

9. #### class MultiChoiceSetting[E <: MultiChoiceEnumeration] extends Setting with Clearable

   A Setting that collects string-valued settings from an enumerated domain.

   A Setting that collects string-valued settings from an enumerated domain.

   - These choices can be turned on or off: "-option:on,-off"
   - If an option is set both on and off, then the option is on
   - The choice "_" enables all choices that have not been explicitly disabled

   Arguments can be provided in colonated or non-colonated mode, i.e. "-option a b" or "-option:a,b". Note that arguments starting with a "-" can only be provided in colonated mode, otherwise they are interpreted as a new option.

   In non-colonated mode, the setting stops consuming arguments at the first non-choice, i.e. "-option a b c" only consumes "a" and "b" if "c" is not a valid choice.

2. #### final def ##(): Int

   Equivalent to `x.hashCode` except for boxed numeric types and `null`. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For `null` returns a hashcode where `null.hashCode` throws a `NullPointerException`.

   returns

     a hash value consistent with ==

     Cast the receiver object to be of type `T0`.

     Cast the receiver object to be of type `T0`.

     Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression `1.asInstanceOf[String]` will throw a `ClassCastException` at runtime, while the expression `List(1).asInstanceOf[List[String]]` will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

     returns

       the receiver object.

     Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

     Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

     The `eq` method implements an equivalence relation on non-null instances of `AnyRef`, and has three additional properties:

     - It is consistent: for any non-null instances `x` and `y` of type `AnyRef`, multiple invocations of `x.eq(y)` consistently returns `true` or consistently returns `false`.
     - For any non-null instance `x` of type `AnyRef`, `x.eq(null)` and `null.eq(x)` returns `false`.
     - `null.eq(null)` returns `true`.

     When overriding the `equals` or `hashCode` methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (`o1 eq o2`), they should be equal to each other (`o1 == o2`) and they should hash to the same value (`o1.hashCode == o2.hashCode`).

     returns

       `true` if the argument is a reference to the receiver object; `false` otherwise.

     Test whether the dynamic type of the receiver object is `T0`.

     Test whether the dynamic type of the receiver object is `T0`.

     Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression `1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

     returns

       `true` if the receiver object is an instance of erasure of type `T0`; `false` otherwise.
