Detailed Description

template<typename T, typename Reader = ValueReader>
class args::ImplicitValueFlag< T, Reader >

An optional argument-accepting flag class.

Template Parameters

T	the type to extract the argument as
Reader	The 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 , typename Reader = ValueReader>

virtual Nargs args::ImplicitValueFlag< T, Reader >::NumberOfArguments ( ) const

inlineoverridevirtualnoexcept

Defines how many values can be consumed by this option.

Returns

closed interval [min, max]

Reimplemented from args::ValueFlagBase.

ParseValue()

template<typename T , typename Reader = ValueReader>

virtual void args::ImplicitValueFlag< T, Reader >::ParseValue ( const std::vector< std::string > &  values_ )

inlineoverridevirtual

Parse values of this option.

Parameters

value

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

Reimplemented from args::ValueFlag< T, ValueReader >.
