std::vector<bool>::reference
< cpp | container | vector bool
| 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
| ~reference() |
||
Destroys the reference.
std::vector<bool>::reference::operator=
| reference& operator=( bool x ); reference& operator=( const reference& x ); |
(until C++11) | |
| reference& operator=( bool x ) noexcept; reference& operator=( const reference& x ) noexcept; |
(since C++11) | |
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)
