Detailed Description

template<typename T, template< typename... > class List = detail::vector, typename Reader = ValueReader>
class args::NargsValueFlag< T, List, Reader >

A variadic arguments accepting flag class.

Template Parameters
Tthe type to extract the argument as
Listthe list type that houses the values
ReaderThe functor type used to read the argument, taking the name, value, and destination reference with operator(), and returning a bool (if ARGS_NOEXCEPT is defined)

Member Function Documentation

◆ NumberOfArguments()

template<typename T , template< typename... > class List = detail::vector, typename Reader = ValueReader>
virtual Nargs args::NargsValueFlag< T, List, Reader >::NumberOfArguments ( ) const
inlineoverridevirtualnoexcept

Defines how many values can be consumed by this option.

Returns
closed interval [min, max]

Implements args::FlagBase.

◆ ParseValue()

template<typename T , template< typename... > class List = detail::vector, typename Reader = ValueReader>
virtual void args::NargsValueFlag< T, List, Reader >::ParseValue ( const std::vector< std::string > &  value)
inlineoverridevirtual

Parse values of this option.

Parameters
valueVector of values. It's size must be in NumberOfArguments() interval.

Implements args::FlagBase.
