** Interface for objects that can be ordering among other
|
|
** objects. The ordering can be <EM>total</EM>, such that two objects
|
|
** only compare equal if they are equal by the equals method, or
|
|
** <EM>partial</EM> such that this is not necessarily true. For
|
|
** example, a case-sensitive dictionary order comparison of Strings
|
|
** is total, but if it is case-insensitive it is partial, because
|
|
** "abc" and "ABC" compare as equal even though "abc".equals("ABC")
|
|
** returns false.
