🔗
stop_source();
1
#
Effects: Initialises *this to have ownership of a new stop state.
2
#
Postconditions: stop_­possible() is true and stop_­requested() is false.
3
#
Throws: bad_­alloc if memory could not be allocated for the stop state.
🔗
explicit stop_source(nostopstate_t) noexcept;
4
#
Postconditions: stop_­possible() is false and stop_­requested() is false.
[Note 1:
No resources are allocated for the state.
— end note]
🔗
stop_source(const stop_source& rhs) noexcept;
5
#
Postconditions: *this == rhs is true.
[Note 2:
*this and rhs share the ownership of the same stop state, if any.
— end note]
🔗
stop_source(stop_source&& rhs) noexcept;
6
#
Postconditions: *this contains the value of rhs prior to the start of construction and rhs.stop_­possible() is false.
🔗
~stop_source();
7
#
Effects: Releases ownership of the stop state, if any.
🔗
stop_source& operator=(const stop_source& rhs) noexcept;
8
#
Effects: Equivalent to: stop_­source(rhs).swap(*this).
9
#
Returns: *this.
🔗
stop_source& operator=(stop_source&& rhs) noexcept;
10
#
Effects: Equivalent to: stop_­source(std​::​move(rhs)).swap(*this).
11
#
Returns: *this.
🔗
void swap(stop_source& rhs) noexcept;
12
#
Effects: Exchanges the values of *this and rhs.
