Examples of jline.ArgumentCompletor

jline.ArgumentCompletor
A {@link Completor} implementation that invokes a child completorusing the appropriate separator argument. This can be used instead of the individual completors having to know about argument parsing semantics.
Example 1: Any argument of the command line can use file completion.
```
 consoleReader.addCompletor (new ArgumentCompletor ( new  {@link FileNameCompletor} ()))
```
Example 2: The first argument of the command line can be completed with any of "foo", "bar", or "baz", and remaining arguments can be completed with a file name.
```
 consoleReader.addCompletor (new ArgumentCompletor ( new  {@link SimpleCompletor} (new String [] { "foo", "bar", "baz"})));consoleReader.addCompletor (new ArgumentCompletor ( new  {@link FileNameCompletor} ()));
```
When the argument index is past the last embedded completors, the last completors is always used. To disable this behavior, have the last completor be a {@link NullCompletor}. For example:
```
 consoleReader.addCompletor (new ArgumentCompletor ( new  {@link SimpleCompletor} (new String [] { "foo", "bar", "baz"}),new  {@link SimpleCompletor} (new String [] { "xxx", "yyy", "xxx"}),new  {@link NullCompletor})); 
```
