>
> The DefaultFormatter is the class that is used to convert an
> {{Entry<Key,Value>}} to the line of text displayed in the shell. Most
> notably, it encodes non-printable ASCII data as hex.
> For users who want to implement their own Formatter, they do not have access
> to the same formatting methods that the DefaultFormatter uses because of the
> visibility modifiers on the methods. These methods should be available for
> use by other classes. Letting classes extend the DefaultFormatter would be
> even better.
> Additionally, in the DefaultFormatter, in the method {{public static String
> formatEntry(Entry<Key,Value>, DateFormat)}}, a StringBuilder is used to
> reduce the number of intermediate String objects that are created for each
> concatenation; however, the methods to get each component of the Key will
> create a new {{Text}} object each time.
> Method invocations like
> {code}
> key.getRow()
> {code}
> Should be replaced with:
> {code}
> Text buffer = new Text();
> key.getRow(buffer);
> {code}
> Where a single {{Text}} object is reused for the entire method.
