- - ### Method Detail

    - #### builder

          public static CommandLine.ParseResult.Builder builder(CommandLine.Model.CommandSpec commandSpec)

      Creates and returns a new `ParseResult.Builder` for the specified command spec.

    - #### matchedOption

          public CommandLine.Model.OptionSpec matchedOption(char shortName)

      Returns the option with the specified short name, or `null` if no option with that name was matched on the command line.

      Use `getValue` on the returned `OptionSpec` to get the matched value (or values), converted to the type of the option. Alternatively, use `stringValues` to get the matched String values after they were split into parts, or `originalStringValues` to get the original String values that were matched on the command line, before any processing.

      To get the default value of an option that was not matched on the command line, use `parseResult.commandSpec().findOption(shortName).getValue()`.

      See Also:
        `CommandLine.Model.CommandSpec.findOption(char)`

    - #### matchedOption

          public CommandLine.Model.OptionSpec matchedOption(String name)

      Returns the option with the specified name, or `null` if no option with that name was matched on the command line.

      Use `getValue` on the returned `OptionSpec` to get the matched value (or values), converted to the type of the option. Alternatively, use `stringValues` to get the matched String values after they were split into parts, or `originalStringValues` to get the original String values that were matched on the command line, before any processing.

      To get the default value of an option that was not matched on the command line, use `parseResult.commandSpec().findOption(String).getValue()`.

      Parameters:
        `name` - used to search the matched options. May be an alias of the option name that was actually specified on the command line. The specified name may include option name prefix characters or not.
      See Also:
