Detailed Description

Boolean argument matcher.

Member Function Documentation

NumberOfArguments()

virtual Nargs args::Flag::NumberOfArguments ( ) const

inlineoverridevirtualnoexcept

Defines how many values can be consumed by this option.

Returns

closed interval [min, max]

Implements args::FlagBase.

ParseValue()

virtual void args::Flag::ParseValue ( const std::vector< std::string > &  value )

inlineoverridevirtual

Parse values of this option.

Parameters

value

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

Implements args::FlagBase.

Reimplemented in args::HelpFlag.
