Constructor Details

SimpleList

public SimpleList()
Create the empty list.

SimpleList

public SimpleList(Object element)
Create a singleton list.
Parameters:
element - The first element.

SimpleList

public SimpleList(Object e1,
                  Object e2)
Create an ordered pair (2-tuple).
Parameters:
e1 - The first element.
e2 - The second element.

SimpleList

public SimpleList(Object e1,
                  Object e2,
                  Object e3)
Create a 3-tuple.
Parameters:
e1 - The first element.
e2 - The second element.
e3 - The third element.

SimpleList

public SimpleList(Object e1,
                  Object e2,
                  Object e3,
                  Object e4)
