boost::proto::transforms_type —
The type used to define the global proto::transforms,
a key for use when creating and accessing a slot in a transform environment for
a set of external transforms.
// In header: <boost/proto/transform/when.hpp> struct transforms_type { // public member functions template<typename Value> env<transforms_type,see-below> operator=(Value &) const; template<typename Value> env<transforms_type,see-below> operator=(Value const &) const; };
The proto::transforms_type type, along with the proto::transforms
global, are declared using the BOOST_PROTO_DEFINE_ENV_VAR() macro.
transforms_type public member functionstemplate<typename Value> env<transforms_type,see-below> operator=(Value & value) const; template<typename Value> env<transforms_type,see-below> operator=(Value const & value) const;
If Value is a specialization boost::reference_wrapper<T>,
this function returns env<transforms_type, T &>(value.get()).
Else, if the type Value is non-copyable (i.e., a function, an array, abstract, or an ostream),
this function returns env<transforms_type, Value ,
where cv &>(value)cvconst for the second overload, and empty
for the first.
Otherwise, this function returns env<transforms_type, Value>(value).
