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; |

Return value
The referenced bit.

void flip(); |
Inverts the referenced bit.
Parameters
(none).
Return value
(none).
