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.

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.

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.

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.

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.

The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.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).

Therefore the expression 1.isInstanceOf[String] will return false, while the

Iterates over the arguments applying them to settings where applicable. Then verifies setting dependencies are met.
This temporarily takes a boolean indicating whether to keep processing if an argument is seen which is not a command line option. This is an expedience for the moment so that you can say
scalac -d /tmp foo.scala -optimise
while also allowing
scala Program opt opt
to get their arguments.
