OptVal

the field of command container which is used to register a option on the command. the name of it is the name of this option. can implicitly convert to bool value same as the result of ArgVal.isValid. T is the innerType of the option or the elemental type of innerType isMandatory true to set it mandatory, default is false, shortAndVal the short flag and value flag(if needed) seperated by space, comma and |
