Iterable Immutable List Assignment

Lists

Lists is a class which holds a number of static methods. As we know, in the Kingdom of Nouns, Verbs must always have an escort.

The first two static methods nil and cons will each call a constructor of the DefaultImmutableList class. The third method brackets will use nil and cons to build up the desired ImmutableList.

class:	Lists.java
methods:	nil cons brackets
package:	immutable.list.assignment
source folder:	src/main/java

nil

public static <E> ImmutableList<E> nil()

Analogous to the SML List nil constructor.

Note: often SML programs use empty brackets [] instead of nil.

cons

public static <E> ImmutableList<E> cons(E head, ImmutableList<E> tail)

Analogous to the SML List :: constructor.

brackets

@SafeVarargs
public static <E> ImmutableList<E> brackets(E... elements)

brackets accepts variable length arguments as specified by the ... syntax.
