This class provides a skeletal implementation of the List
interface to minimize the effort required to implement this interface
backed by a "sequential access" data store (such as a linked list). For
random access data (such as an array), AbstractList should be used
in preference to this class.
This class is the opposite of the AbstractList class in the sense
that it implements the "random access" methods (get(int index),
set(int index, Object element), set(int index, Object
element), add(int index, Object element) and remove(int
index)) on top of the list's list iterator, instead of the other way
around.
To implement a list the programmer needs only to extend this class and
provide implementations for the listIterator and size
methods. For an unmodifiable list, the programmer need only implement the
list iterator's hasNext, next, hasPrevious,
previous and index methods.
For a modifiable list the programmer should additionally implement the list
iterator's set method. For a variable-size list the programmer
should additionally implement the list iterator's remove and
add methods.
The programmer should generally provide a void (no argument) and collection
constructor, as per the recommendation in the Collection interface
specification.
This class is a member of the
Java Collections Framework.
