Class JOptCommandLinePropertySource


  • public class JOptCommandLinePropertySource
    extends CommandLinePropertySource<joptsimple.OptionSet>
    CommandLinePropertySource implementation backed by a JOpt OptionSet.

    Typical usage

    Configure and execute an OptionParser against the String[] of arguments supplied to the main method, and create a JOptCommandLinePropertySource using the resulting OptionSet object:
     public static void main(String[] args) {
         OptionParser parser = new OptionParser();
         parser.accepts("option1");
         parser.accepts("option2").withRequiredArg();
         OptionSet options = parser.parse(args);
         PropertySource
           ps = new JOptCommandLinePropertySource(options);
         // ...
     }
    See CommandLinePropertySource for complete general usage examples.

    Requires JOpt version 3.0 or higher. Tested against JOpt up until 4.6.

        Description copied from class: CommandLinePropertySource
        Return the collection of values associated with the command line option having the given name.
        • if the option is present and has no argument (e.g.: "--foo"), return an empty collection ([])
        • if the option is present and has a single value (e.g. "--foo=bar"), return a collection having one element (["bar"])
        • if the option is present and the underlying command line parsing library supports multiple arguments (e.g. "--foo=bar --foo=baz"), return a collection having elements for each value (["bar", "baz"])
        • if the option is not present, return null
