Interface
|
||
|
|
========================================
|
||
|
|
.. sourcecode:: c++
|
||
|
|
|
||
|
|
void swap(basic_string& s) SPROUT_NOEXCEPT_EXPR(SPROUT_NOEXCEPT_EXPR(std::swap(std::declval<T&>(), std::declval<T&>())));
|
||
|
|
|
||
|
|
Postcondition
|
||
|
|
========================================
|
||
|
|
|
||
|
|
| ``*this`` contains the same sequence of characters that was in s, s contains the same sequence of characters that was in ``*this``.
|
||
|
|
|
||
|
|
Throws
|
||
|
|
========================================
|
||
|
|
|
||
|
|
| Nothing unless one of the element-wise swap calls throws an exception.
|
||
|
|
|
||
|

Examples
|
||
|
|
========================================
|
||
|
|
.. sourcecode:: c++

|
auto y = string<8>("madocchi");
|
||
|
|

|
||
|
|
SPROUT_ASSERT_MSG(x == "madocchi" && y == "homuhomu", "each element are swapped.");
