std::vector<bool>::reference (3) - Linux Man Pages

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

NAME

std::vector<bool>::reference - std::vector<bool>::reference

Synopsis


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


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


 std::vector<bool>::reference::~reference


~reference()


Destroys the reference.


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


reference& operator=( bool x ); (until C++11)
reference& operator=( const reference& x );
reference& operator=( bool x ) noexcept; (since C++11)
reference& operator=( const reference& x ) noexcept;


Assigns a value to the referenced bit.

Parameters


x - value to assign

Return value


*this


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


operator bool() const; (until C++11)
operator bool() const noexcept; (since C++11)


Returns the value of the referenced bit.

Parameters


(none)

Return value


The referenced bit.


 std::vector<bool>::reference::flip


void flip(); (until C++11)
void flip() noexcept; (since C++11)


Inverts the referenced bit.

Parameters


(none)

Return value


(none)
