as_table =========== *make sure an object is pushed as a table* .. code-block:: cpp template as_table_t { T& value() &; const T& value() & const; T&& value() &&; }; template as_table_t as_function ( T&& container ); This function serves the purpose of ensuring that an object is pushed -- if possible -- like a table into Lua. The container passed here can be a pointer, a reference, a ``std::reference_wrapper`` around a container, or just a plain container value. It must have a begin/end function, and if it has a ``std::pair`` as its ``value_type``, it will be pushed as a dictionary. Otherwise, it's pushed as a sequence. .. literalinclude:: ../../../examples/source/docs/as_table_ipairs.cpp :linenos: Note that any caveats with Lua tables apply the moment it is serialized, and the data cannot be gotten out back out in C++ as a C++ type. You can deserialize the Lua table into something explicitly using the ``sol::as_table_t`` marker for your get and conversion operations using sol. At that point, the returned type is deserialized **from** a table, meaning you cannot reference any kind of C++ data directly as you do with regular userdata/usertypes. *All C++ type information is lost upon serialization into Lua.* If you need this functionality with a member variable, use a :doc:`property on a getter function` that returns the result of ``sol::as_table``. This marker does NOT apply to :doc:`usertypes`. You can also use this to nest types and retrieve tables within tables as shown by this example. .. literalinclude:: ../../../examples/source/containers_as_table.cpp :linenos: :lines: 1-8,31-60,62-68,70-
