Interface defining a command-line interface (in other words a command such as 'run', 'ls'…). This interface is polyglot to ease reuse such as in Vert.x Shell.

A command line interface has a name, and defines a set of options and arguments. Options are key-value pair such as `-foo=bar` or `-flag`. The supported formats depend on the used parser. Arguments are unlike options raw values. Options are defined using Option, while argument are defined using Argument.

Command line interfaces also define a summary and a description. These attributes are used in the usage generation . To disable the help generation, set the `hidden` attribute to `true`.

Command Line Interface object does not contains “value”, it's a model. It must be evaluated by a parser that returns a CommandLine object containing the argument and option values.

Methods
`addArgument` | `shared default CLI addArgument(Argument arg)` Adds an argument. Parameters: `arg` the argument, must not be `null`
`addArguments` | `shared default CLI addArguments(List<Argument> args)` Adds a set of arguments. Unlike setArguments, this method does not remove the existing arguments. The given list is appended to the existing list. Parameters: `args` the arguments, must not be `null`
`addOption` | `shared default CLI addOption(Option option)` Adds an option. Parameters: `option` the option, must not be `null`.
`addOptions` | `shared default CLI addOptions(List<Option> options)` Adds a set of options. Unlike setOptions}, this method does not remove the existing options. The given list is appended to the existing list. Parameters: `options` the options, must not be `null`
`getArgument` | `shared default Argument? getArgument(Integer index)` Gets an Argument based on its index. Parameters: `index` the index, must be positive or zero.
`getArgument` | `shared default Argument? getArgument(String name)` Gets an Argument based on its name (argument name). Parameters: `name` the name of the argument, must not be `null`
`getArguments` | `shared default List<Argument> getArguments()` Gets the list of defined arguments.
`getDescription` | `shared default String? getDescription()`
`getName` | `shared default String getName()`
`getOption` | `shared default Option? getOption(String name)` Gets an Option based on its name (short name, long name or argument name). Parameters: `name` the name, must not be `null`
`getOptions` | `shared default List<Option> getOptions()` Gets the list of options.
`getSummary` | `shared default String? getSummary()`
`isHidden` | `shared default Boolean isHidden()` Checks whether or not the current CLI instance is hidden.
`parse` | `shared default CommandLine parse(List<String> arguments)` Parses the user command line interface and create a new CommandLine containing extracting values. Parameters: `arguments` the arguments
`parse` | `shared default CommandLine parse(List<String> arguments, Boolean validate)` Parses the user command line interface and create a new CommandLine containing extracting values. Parameters: `arguments` the arguments `validate` enable / disable parsing validation
`removeArgument` | `shared default CLI removeArgument(Integer index)` Removes an argument identified by its index. This method does nothing if the argument cannot be found. Parameters: `index` the argument index
`removeOption` | `shared default CLI removeOption(String name)` Removes an option identified by its name. This method does nothing if the option cannot be found. Parameters: `name` the option name
`setArguments` | `shared default CLI setArguments(List<Argument> args)` Sets the list of arguments. Parameters: `args` the list of arguments, must not be `null`
`setDescription` | `shared default CLI setDescription(String desc)`
`setHidden` | `shared default CLI setHidden(Boolean hidden)` Sets whether or not the current instance of CLI must be hidden. Hidden CLI are not listed when displaying usages / help messages. In other words, hidden commands are for power user. Parameters: `hidden` enables or disables the hidden aspect of the CI
`setName` | `shared default CLI setName(String name)` Sets the name of the CLI. Parameters: `name` the name
`setOptions` | `shared default CLI setOptions(List<Option> options)` Sets the list of arguments. Parameters: `options` the list of options, must not be `null`
`setSummary` | `shared default CLI setSummary(String summary)` Sets the summary of the CLI. Parameters: `summary` the summary
