public class Polylist

extends Object

    Polylist is the basic unit for constructing an open linked list of Objects.
    A Polylist can be either :
      empty, or
      non-empty, in which case it consists of:
           a Object as the first thing in the list
           a rest which is a Polylist.
    A Polylist can also be a Incremental, which may be converted into an
    ordinary Polylist by applying methods such as isEmpty(), first(), and
    rest(). 
  

nil

nil is the empty-list constant

Polylist()

construct empty Polylist

analysis(Object)

analysis produces a string analyzing objects, especially Polylists

append(Polylist)

append(M) returns a Polylist consisting of the elements of this followed by those of M.

array()

array() returns an array of elements in list

cons(Object)

cons returns a new Polylist given a First and this as a Rest

cons(Object, Polylist)

static cons returns a new Polylist given a First and a Rest.

cons(Object, Seed)

This variant of cons takes a Seed instead of a Polylist as rest, so the list can be grown incrementally.

coprefix(long)

coprefix creates the Polylist with all but the length-n prefix of a Polylist

elements()

elements() returns a PolylistEnum object, which implements the interface java.util.Enumeration.

equals(Polylist)

equals(M) tells whether this Polylist is equal to some other

equals(Polylist, Polylist)

equals(L, M) tells whether Polylists L and M are equal

explode(String)
