/**

* 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.
