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)
Test
class:
ListsTestSuite.java
package:
immutable.list.assignment
source folder:
src/test/java
