Class CommandLine.ParseResult

Method Details

• builder

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

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

• findMatches

  public List<CommandLine.ParseResult.GroupMatchContainer> findMatches(CommandLine.Model.ArgGroupSpec group)

  Returns the matches for the specified argument group.

• getGroupMatches

  public List<CommandLine.ParseResult.GroupMatch> getGroupMatches()

  Returns the top-level container for the ArgGroupSpec match or matches found.

  If the user input was a valid combination of group arguments, the returned list should contain a single match. Details of the matched groups encountered on the command line can be obtained via its matchedSubgroups() method. The top-level match returned by this method contains no matched arguments.

  If the returned list contains more than one match, the user input was invalid: the maximum multiplicity of a group was exceeded, and the parser created an extra match to capture the values. Usually this results in a ParameterException being thrown by the parse method, unless the parser is configured to collect errors.

• 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().

  • 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.

• hasMatchedOption

  public boolean hasMatchedOption(char shortName)

• matchedOptions

  public List<CommandLine.Model.OptionSpec> matchedOptions()

  Returns a list of matched options, in order they were matched on the command line. The returned list may contain the same OptionSpec multiple times, if the option was matched multiple times on the command line.

• matchedPositionals

  public List<CommandLine.Model.PositionalParamSpec> matchedPositionals()

  Returns a list of matched positional parameters, in order they were matched on the command line. The returned list may contain the same PositionalParamSpec multiple times, if the parameter was matched multiple times on the command line.

• matchedArgs

  public List<CommandLine.Model.ArgSpec> matchedArgs()

  Returns a list of matched options and positional parameters, in order they were matched on the command line. The returned list may contain an OptionSpec or PositionalParamSpec multiple times, if the option or parameter was matched multiple times on the command line.

• unmatched

  public List<String> unmatched()

  Returns a list of command line arguments that did not match any options or positional parameters.

• originalArgs

  public List<String> originalArgs()

  Returns the command line arguments that were parsed.

• errors

  public List<Exception> errors()

  Returns the command line argument value of the option with the specified name, converted to the type of the option, or the specified default value if no option with the specified name was matched.

• matchedPositionalValue

  public <T> T matchedPositionalValue(int position, T defaultValue)

  Returns the command line argument value of the positional parameter at the specified position, converted to the type of the positional parameter, or the specified default value if no positional parameter was matched at that position.
