类 JOptCommandLinePropertySource

java.lang.Object
cn.taketoday.core.env.PropertySource<T>
cn.taketoday.core.env.EnumerablePropertySource<T>
cn.taketoday.core.env.CommandLinePropertySource<joptsimple.OptionSet>
cn.taketoday.core.env.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.

If an option has several representations, the most descriptive is expected to be set last, and is used as the property name of the associated EnumerablePropertySource.getPropertyNames().

See CommandLinePropertySource for complete general usage examples.

Requires JOpt Simple version 4.3 or higher. Tested against JOpt up until 5.0.

    • containsOption

      protected boolean containsOption(String name)
      从类复制的说明: CommandLinePropertySource
      Return whether the set of option arguments parsed from the command line contains an option with the given name.
      指定者:
      containsOption 在类中 CommandLinePropertySource<joptsimple.OptionSet>

    • getPropertyNames

      @NonNull public String[] getPropertyNames()
      从类复制的说明: EnumerablePropertySource
      Return the names of all properties contained by the source object (never null).
      指定者:
      getPropertyNames 在类中 EnumerablePropertySource<joptsimple.OptionSet>

    • getOptionValues

      @Nullable public List<String> getOptionValues(String name)
      从类复制的说明: 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
      指定者:
      getOptionValues 在类中 CommandLinePropertySource<joptsimple.OptionSet>

    • getNonOptionArgs

      protected List<String> getNonOptionArgs()
      从类复制的说明: CommandLinePropertySource
      Return the collection of non-option arguments parsed from the command line. Never null.
      指定者:
      getNonOptionArgs 在类中 CommandLinePropertySource<joptsimple.OptionSet>
