* These classes are intended to be used as singletons. There is no need

* settings. Thus most styles can be achieved without subclassing.
|
||||
* <p>
|
||||
* If required, a subclass can override as many or as few of the methods as
|
||||
* it requires.Each object type (from boolean to long to Object to int[]) has
|
||||
* its own methods to output it. Most have two versions, detail and summary. For
|
||||
* example, the detail version of the array based methods will output the
|
||||
* whole array, whereas the summary method will just output the array length.
