类 JOptCommandLinePropertySource

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

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.

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

从以下版本开始:
4.0

    • 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>
