Public Types
using	filter_fn_t = std::function< std::string(std::string)>

Public Member Functions
template<typename T , typename... Args>
	IsMember (std::initializer_list< T > values, Args &&...args)
	This allows in-place construction using an initializer list.
template<typename T >
	IsMember (T &&set)
	This checks to see if an item is in a set (empty function)
template<typename T , typename F >
	IsMember (T set, F filter_function)
template<typename T , typename... Args>
	IsMember (T &&set, filter_fn_t filter_fn_1, filter_fn_t filter_fn_2, Args &&...other)
	You can pass in as many filter functions as you like, they nest (string only currently)
Public Member Functions inherited from CLI::Validator
	Validator ()=default
	Validator (std::string validator_desc)
	Construct a Validator with just the description string.
	Validator (std::function< std::string(std::string &)> op, std::string validator_desc, std::string validator_name="")
	Construct Validator from basic information.
Validator &	operation (std::function< std::string(std::string &)> op)
	Set the Validator operation function.
std::string	operator() (std::string &str) const
std::string	operator() (const std::string &str) const
Validator &	description (std::string validator_desc)
	Specify the type string.
Validator	description (std::string validator_desc) const
	Specify the type string.
std::string	get_description () const
	Generate type description information for the Validator.
Validator &	name (std::string validator_name)
	Specify the type string.
Validator	name (std::string validator_name) const
	Specify the type string.
const std::string &	get_name () const
	Get the name of the Validator.
Validator &	active (bool active_val=true)
	Specify whether the Validator is active or not.
Validator	active (bool active_val=true) const
	Specify whether the Validator is active or not.
Validator &	non_modifying (bool no_modify=true)
	Specify whether the Validator can be modifying or not.
Validator &	application_index (int app_index)
	Specify the application index of a validator.
Validator	application_index (int app_index) const
	Specify the application index of a validator.
int	get_application_index () const
	Get the current value of the application index.
bool	get_active () const
	Get a boolean if the validator is active.
bool	get_modifying () const
	Get a boolean if the validator is allowed to modify the input returns true if it can modify the input.
Validator	operator& (const Validator &other) const
Validator	operator| (const Validator &other) const
Validator	operator! () const
	Create a validator that fails when a given validator succeeds.

Additional Inherited Members
Protected Attributes inherited from CLI::Validator
std::function< std::string()>	desc_function_ {[]() { return std::string{}; }}
	This is the description function, if empty the description_ will be used.
std::function< std::string(std::string &)>	func_ {[](std::string &) { return std::string{}; }}
std::string	name_ {}
	The name for search purposes of the Validator.
int	application_index_ = -1
	A Validator will only apply to an indexed value (-1 is all elements)
bool	active_ {true}
	Enable for Validator to allow it to be disabled if need be.
bool	non_modifying_ {false}
	specify that a validator should not modify the input

Detailed Description

Verify items are in a set.

Member Typedef Documentation

filter_fn_t

using CLI::IsMember::filter_fn_t = std::function<std::string(std::string)>

Constructor & Destructor Documentation

IsMember() [1/4]

template<typename T , typename... Args>

CLI::IsMember::IsMember ( std::initializer_list< T >  values, Args &&...  args  )

inline

This allows in-place construction using an initializer list.

IsMember() [2/4]

template<typename T >

CLI::IsMember::IsMember ( T &&  set )

inlineexplicit

This checks to see if an item is in a set (empty function)

IsMember() [3/4]

template<typename T , typename F >

CLI::IsMember::IsMember ( T  set, F  filter_function  )

inlineexplicit

This checks to see if an item is in a set: pointer or copy version. You can pass in a function that will filter both sides of the comparison before computing the comparison.

IsMember() [4/4]

template<typename T , typename... Args>

CLI::IsMember::IsMember ( T &&  set, filter_fn_t  filter_fn_1, filter_fn_t  filter_fn_2, Args &&...  other  )

inline

You can pass in as many filter functions as you like, they nest (string only currently)
