| |
| +-----------------------+---------------------------+-----------------------------------+ |
| | Parameter | Requirement | Description | |
| +=======================+===========================+===================================+ |
| | ``Sequence1``, | |Forward Sequence| | Sequences to create a view on. | |
| | ``Sequence2`` | | | |
| +-----------------------+---------------------------+-----------------------------------+ |

| Expression semantics |
| -------------------- |
| |
| |Semantics disclaimer...| |Forward Sequence|. |
| |
| In the following table, ``v`` is an instance of ``joint_view``, ``s1`` and ``s2`` are arbitrary |
| |Forward Sequence|\ s. |
| |
| +-------------------------------+-----------------------------------------------------------+ |
| | Expression | Semantics | |
| +===============================+===========================================================+ |
| | .. parsed-literal:: | A lazy |Forward Sequence| of all the elements in the | |
| | | ranges |begin/end<s1>|, |begin/end<s2>|. | |
| | joint_view<s1,s2> | | |
| | joint_view<s1,s2>::type | | |
| +-------------------------------+-----------------------------------------------------------+ |
| | ``size<v>::type`` | The size of ``v``; | |
| | | ``size<v>::value == size<s1>::value + size<s2>::value``; | |
| | | linear complexity; see |Forward Sequence|. | |
