\brief Converts a sequence to a Boost PP array whose elements are the elements of the sequence.

|
|
... = Variadic parameters.
|
||
|
|
|
||
|
|
The first variadic parameter is required and is the sequence to convert.
|
||
|
|
|
||
|
|
Further optional variadic parameters can be return type parameters. Return type
|
||
|
|
parameters allow each element in the sequence to be converted to a two-element
|
||
|
|
tuple where the first tuple element is the type and the second tuple element
|
||
|
|
is the element data.
|
||
|
|
|
||
|
|
The BOOST_VMD_RETURN_NO_TYPE, the default, does not return the type as part of each
|
||
|
|
converted element but just the data. All of the rest return the type and data as the
|
||
|
|
two-element tuple. If BOOST_VMD_RETURN_TYPE is specified the specific type of the element
|
||
|
|
is returned in the tuple. If BOOST_VMD_RETURN_TYPE_ARRAY is specified an array type is
|
||
|
|
returned if the element is an array, else a tuple type is returned if the element is a tuple,
|
||
|
|
else the actual type is returned for non-tuple data. If BOOST_VMD_RETURN_TYPE_LIST is specified
|
||
|
|
a list type is returned if the element is a list, else a tuple type is returned if the element
|
||
|
|
is a tuple, else the actual type is returned for non-tuple data. If BOOST_VMD_RETURN_TYPE_TUPLE
|
||
|
|
is specified a tuple type is returned for all tuple-like data, else the actual type is returned
|
||
|
|
for non-tuple data. If more than one return type optional parameter is specified the last one
|
||
|
|
specified determines the return type.
|
||
|
|
|
||
|
|
returns = A Boost PP array. The sequence is empty the Boost PP array is an empty array.
|
||
|
|
If an optional return type other than BOOST_VMD_RETURN_NO_TYPE
|
||
|
|
is specified the type and the data of each element is
|
||
|
|
returned as the array element. Otherwise just the data
|
||
|
|
is returned as the array element, which is the default.
