public CommandInfo[] getPreferredCommands(String mimeType, DataSource ds)
The DataSource
provides extra information, such as
the file name, that a CommandMap implementation may use to further
refine the list of commands that are returned. The implementation
in this class simply calls the getPreferredCommands
method that ignores this argument.

in this class simply calls the getCommand
method that ignores this argument.
