/** \def BOOST_VMD_GET_TYPE(...)
|
|
\brief Returns the type of a sequence as a VMD type.
|
|
... = variadic parameters.
|
|
The first variadic parameter is required and is the sequence whose type we are getting.
|
|
The optional variadic parameters are return type parameters.
|
|
The macro returns the type of a sequence as a VMD type. The type of an empty sequence
|
is always BOOST_VMD_TYPE_EMPTY and the type of a multi-element is always
|
BOOST_VMD_TYPE_SEQUENCE. The type of a single-element sequence is the
|
type of that single element.
|
|
The type returned can be modified by specifying an optional return type parameter.
|
|
If BOOST_VMD_RETURN_TYPE, the default, is specified the specific type of the element
|
is returned.
|
|
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 BOOST_VMD_RETURN_NO_TYPE is specified it is ignored since the macro
|
always returns the type of the sequence.
|
|
If more than one return type optional parameter is specified the last
|
one specified determines the return type.
|
|
returns = the type of the sequence as a VMD type.
