public class TestCompleter
extends java.lang.Object
implements ReadlineCompleter
This class is a sample custom completer. If you press the TAB-key at
the readline prompt, you will see the two possible completions ("Linux"
and "Tux"). Once you have entered a "L" or a "T", you will only see
the respective single possible completion. In any other case, null is
returned to signal that no (more) completions are available.
t - start of completion text. This is the text since the last
word break character.
s - 0 or positive int. This state is zero on the first call
for a completion request and increments for each subsequent
call until the end of choices is reached.
Returns:
String with a completion choice or null, if there
are no more choices.
