{{{1}}}& operator=( const {{{1}}}& other );
(1) قالب:mark since none

Replaces the contents of the container.

1) Copy assignment operator. Replaces the contents with a copy of the contents of ‎other‎.If std::allocator_traits<allocator_type>::propagate_on_container_copy_assignment()‎ is true, the target allocator is replaced by a copy of the source allocator. If the target and the source allocators do not compare equal, the target (*this) allocator is used to deallocate the memory, then ‎other‎'s allocator is used to allocate it before copying the elements. (since C++11)
2) Move assignment operator. Replaces the contents with those of ‎other‎ using move semantics (i.e. the data in ‎other‎ is moved from ‎other‎ into this container). ‎other‎ is in a valid but unspecified state afterwards. If std::allocator_traits<allocator_type>::propagate_on_container_move_assignment()‎ is true, the target allocator is replaced by a copy of the source allocator. If it is false and the source and the target allocators do not compare equal, the target cannot take ownership of the source memory and must move-assign each element individually, allocating additional memory using its own allocator as needed.
3) Replaces the contents with those identified by initializer list ‎ilist‎.

[تعديل] Parameters

other - another container to use as data source
ilist - initializer list to use as data source

[تعديل] Return value

*this

[تعديل] Complexity

1) Linear in the size of the ‎other‎.
2) Constant unless std::allocator_traits<allocator_type>::propagate_on_container_move_assignment()‎ is false and the allocators do not compare equal (in which case linear).
3) Linear in the size of ‎ilist‎.
