class reference;

The std::vector<bool> specialization defines std::vector<bool>::reference as a publicly-accessible nested class. std::vector<bool>::reference proxies the behavior of references to a single bit in std::vector<bool>.

The primary use of std::vector<bool>::reference is to provide an l-value that can be returned from operator[].

Any reads or writes to a vector that happen via a std::vector<bool>::reference potentially read or write to the entire underlying vector.

Member functions

(constructor)	constructs the reference. Accessible only to std::vector<bool> itself (public member function)
(destructor)	destroys the reference (public member function)
operator=	assigns a bool to the referenced bit (public member function)
operator bool	returns the referenced bit (public member function)
flip	flips the referenced bit (public member function)

std::vector<bool>::~reference

~reference()

Destroys the reference.

std::vector<bool>::reference::operator=

reference& operator=( bool x ); reference& operator=( const reference& x );

Assigns a value to the referenced bit.

Parameters

x

-

value to assign

Return value

*this

Exceptions

(none)	(until C++11)
noexcept specification:   noexcept	(since C++11)

std::vector<bool>::reference::operator bool

operator bool() const;

Parameters

Return value

noexcept specification:   noexcept	(since C++11)

std::vector<bool>::reference::flip

void flip();

Inverts the referenced bit.

Parameters

(none)

Return value

(none)
