std::vector<bool>::reference

From cppreference.com
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
