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.

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.

10. #### class MultiStringSetting extends Setting with Clearable

    A setting that accumulates all strings supplied to it, until it encounters one starting with a '-'.

11. #### class OutputDirs extends AnyRef

    A class for holding mappings from source directories to their output location.

    A class for holding mappings from source directories to their output location. This functionality can be accessed only programmatically. The command line compiler uses a single output location, but tools may use this functionality to set output location per source directory.

12. #### class OutputSetting extends StringSetting

    Set the output directory.

13. #### class PathSetting extends StringSetting

14. #### class PhasesSetting extends Setting with Clearable

    A setting represented by a list of strings which should be prefixes of phase names.

    A setting represented by a list of strings which should be prefixes of phase names. This is not checked here, however. Alternatively the string `"all"` can be used to represent all phases. (the empty list, unless set)

15. #### class PrefixSetting extends Setting

    A special setting for accumulating arguments like -Dfoo=bar.

17. #### class ScalaVersionSetting extends Setting

    A setting represented by a Scala version.

    A setting represented by a Scala version. The `initial` value is used if the setting is not specified. The `default` value is used if the option is specified without argument (e.g., `-Xmigration`).

18. #### abstract class Setting extends AbsSetting with SettingValue with Mutable

    A base class for settings of all types.

    A base class for settings of all types. Subclasses each define a `value` field of the appropriate type.

20. #### class StringSetting extends Setting

    A setting represented by a string, (`default` unless set)

### Value Members

   Test two objects for inequality.

   Test two objects for inequality.

   returns

     `true` if !(this == that), false otherwise.

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

   Equivalent to `x.hashCode` except for boxed numeric types and `null`.

   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 ==

99. #### final def asInstanceOf[T0]: T0

    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.

129. #### final def eq(arg0: AnyRef): Boolean

     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.

157. #### final def isInstanceOf[T0]: Boolean

     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.
